The adaption of means to ends in nature clearly indicates a ——, and so proves a ——er. The changes made by living systems in response to their environment.

Heavy fur, for example, is one adaptation to a cold climate. For all you Beatles fans across the universe, all you need is this quiz to prove how well you know your Beatles music.

Stanley in Africa James P. King John of Jingalo Laurence Housman. Sheppard Lee, Vol. I of 2 Robert Montgomery Bird. Often, two or more species co-adapt and co-evolve as they develop adaptations that interlock with those of the other species, such as with flowering plants and pollinating insects.

In mimicry , species evolve to resemble other species; in Müllerian mimicry this is a mutually beneficial co-evolution as each of a group of strongly defended species such as wasps able to sting come to advertise their defences in the same way.

Features evolved for one purpose may be co-opted for a different one, as when the insulating feathers of dinosaurs were co-opted for bird flight.

Adaptation is a major topic in the philosophy of biology , as it concerns function and purpose teleology.

Some biologists try to avoid terms which imply purpose in adaptation, not least because it suggests a deity's intentions, but others note that adaptation is necessarily purposeful.

Adaptation is an observable fact of life accepted by philosophers and natural historians from ancient times, independently of their views on evolution , but their explanations differed.

Empedocles did not believe that adaptation required a final cause a purpose , but thought that it "came about naturally, since such things survived.

In natural theology , adaptation was interpreted as the work of a deity and as evidence for the existence of God. Pangloss [3] is a parody of this optimistic idea, and David Hume also argued against design.

The series was lampooned by Robert Knox , who held quasi-evolutionary views, as the Bilgewater Treatises. Charles Darwin broke with the tradition by emphasising the flaws and limitations which occurred in the animal and plant worlds.

Jean-Baptiste Lamarck proposed a tendency for organisms to become more complex, moving up a ladder of progress, plus "the influence of circumstances," usually expressed as use and disuse.

Other natural historians, such as Buffon , accepted adaptation, and some also accepted evolution, without voicing their opinions as to the mechanism.

This illustrates the real merit of Darwin and Alfred Russel Wallace , and secondary figures such as Henry Walter Bates , for putting forward a mechanism whose significance had only been glimpsed previously.

A century later, experimental field studies and breeding experiments by people such as E. Ford and Theodosius Dobzhansky produced evidence that natural selection was not only the 'engine' behind adaptation, but was a much stronger force than had previously been thought.

The significance of an adaptation can only be understood in relation to the total biology of the species. Adaptation is primarily a process rather than a physical form or part of a body.

From this we see that adaptation is not just a matter of visible traits: in such parasites critical adaptations take place in the life cycle , which is often quite complex.

Many aspects of an animal or plant can be correctly called adaptations, though there are always some features whose function remains in doubt.

By using the term adaptation for the evolutionary process , and adaptive trait for the bodily part or function the product , one may distinguish the two different senses of the word.

Adaptation is one of the two main processes that explain the observed diversity of species, such as the different species of Darwin's finches.

The other process is speciation , in which new species arise, typically through reproductive isolation. Adaptation is not always a simple matter where the ideal phenotype evolves for a given environment.

An organism must be viable at all stages of its development and at all stages of its evolution.

This places constraints on the evolution of development, behaviour, and structure of organisms. The main constraint, over which there has been much debate, is the requirement that each genetic and phenotypic change during evolution should be relatively small, because developmental systems are so complex and interlinked.

However, it is not clear what "relatively small" should mean, for example polyploidy in plants is a reasonably common large genetic change.

All adaptations help organisms survive in their ecological niches. The adaptive traits may be structural, behavioural or physiological.

Structural adaptations are physical features of an organism, such as shape, body covering, armament, and internal organization.

Behavioural adaptations are inherited systems of behaviour, whether inherited in detail as instincts , or as a neuropsychological capacity for learning.

Examples include searching for food , mating , and vocalizations. Physiological adaptations permit the organism to perform special functions such as making venom , secreting slime , and phototropism , but also involve more general functions such as growth and development , temperature regulation , ionic balance and other aspects of homeostasis.

Adaptation affects all aspects of the life of an organism. The following definitions are given by the evolutionary biologist Theodosius Dobzhansky :.

Adaptation differs from flexibility, acclimatization , and learning, all of which are changes during life which are not inherited.

Flexibility deals with the relative capacity of an organism to maintain itself in different habitats: its degree of specialization.

Acclimatization describes automatic physiological adjustments during life; [30] learning means improvement in behavioral performance during life.

Flexibility stems from phenotypic plasticity , the ability of an organism with a given genotype genetic type to change its phenotype observable characteristics in response to changes in its habitat , or to move to a different habitat.

A highly specialized animal or plant lives only in a well-defined habitat, eats a specific type of food, and cannot survive if its needs are not met.

Many herbivores are like this; extreme examples are koalas which depend on Eucalyptus , and giant pandas which require bamboo. A generalist, on the other hand, eats a range of food, and can survive in many different conditions.

Examples are humans, rats , crabs and many carnivores. The tendency to behave in a specialized or exploratory manner is inherited—it is an adaptation.

Rather different is developmental flexibility: "An animal or plant is developmentally flexible if when it is raised in or transferred to new conditions, it changes in structure so that it is better fitted to survive in the new environment," writes evolutionary biologist John Maynard Smith.

If humans move to a higher altitude, respiration and physical exertion become a problem, but after spending time in high altitude conditions they acclimatize to the reduced partial pressure of oxygen, such as by producing more red blood cells.

The ability to acclimatize is an adaptation, but the acclimatization itself is not. The reproductive rate declines, but deaths from some tropical diseases also go down.

Over a longer period of time, some people are better able to reproduce at high altitudes than others. They contribute more heavily to later generations, and gradually by natural selection the whole population becomes adapted to the new conditions.

This has demonstrably occurred, as the observed performance of long-term communities at higher altitude is significantly better than the performance of new arrivals, even when the new arrivals have had time to acclimatize.

There is a relationship between adaptedness and the concept of fitness used in population genetics. Differences in fitness between genotypes predict the rate of evolution by natural selection.

Natural selection changes the relative frequencies of alternative phenotypes, insofar as they are heritable.

Dobzhansky mentioned the example of the Californian redwood , which is highly adapted, but a relict species in danger of extinction.

Sewall Wright proposed that populations occupy adaptive peaks on a fitness landscape. To evolve to another, higher peak, a population would first have to pass through a valley of maladaptive intermediate stages, and might be "trapped" on a peak that is not optimally adapted.

Before Darwin, adaptation was seen as a fixed relationship between an organism and its habitat. It was not appreciated that as the climate changed, so did the habitat; and as the habitat changed, so did the biota.

Also, habitats are subject to changes in their biota: for example, invasions of species from other areas. The relative numbers of species in a given habitat are always changing.

Change is the rule, though much depends on the speed and degree of the change. When the habitat changes, three main things may happen to a resident population: habitat tracking, genetic change or extinction.

In fact, all three things may occur in sequence. Of these three effects only genetic change brings about adaptation. When a habitat changes, the resident population typically moves to more suitable places; this is the typical response of flying insects or oceanic organisms, which have wide though not unlimited opportunity for movement.

It is one explanation put forward for the periods of apparent stasis in the fossil record the punctuated equilibrium theory.

Genetic change occurs in a population when natural selection and mutations act on its genetic variability.

By this means, the population adapts genetically to its circumstances. The varying shapes of the beaks of Darwin's finches, for example, are driven by differences in the ALX1 gene.

Habitats and biota do frequently change. Therefore, it follows that the process of adaptation is never finally complete.

On the other hand, it may happen that changes in the environment occur relatively rapidly, and then the species becomes less and less well adapted.

Seen like this, adaptation is a genetic tracking process , which goes on all the time to some extent, but especially when the population cannot or does not move to another, less hostile area.

Given enough genetic change, as well as specific demographic conditions, an adaptation may be enough to bring a population back from the brink of extinction in a process called evolutionary rescue.

Adaptation does affect, to some extent, every species in a particular ecosystem. Leigh Van Valen thought that even in a stable environment, competing species constantly had to adapt to maintain their relative standing.

This became known as the Red Queen hypothesis , as seen in host- parasite interaction. Existing genetic variation and mutation were the traditional sources of material on which natural selection could act.

In addition, horizontal gene transfer is possible between organisms in different species, using mechanisms as varied as gene cassettes , plasmids , transposons and viruses such as bacteriophages.

In coevolution , where the existence of one species is tightly bound up with the life of another species, new or 'improved' adaptations which occur in one species are often followed by the appearance and spread of corresponding features in the other species.

These co-adaptational relationships are intrinsically dynamic, and may continue on a trajectory for millions of years, as has occurred in the relationship between flowering plants and pollinating insects.

Bates' work on Amazonian butterflies led him to develop the first scientific account of mimicry , especially the kind of mimicry which bears his name: Batesian mimicry.

Mimicry is thus an anti-predator adaptation. A common example seen in temperate gardens is the hoverfly , many of which—though bearing no sting—mimic the warning coloration of hymenoptera wasps and bees.

Such mimicry does not need to be perfect to improve the survival of the palatable species. Bates, Wallace and Fritz Müller believed that Batesian and Müllerian mimicry provided evidence for the action of natural selection , a view which is now standard amongst biologists.

It is a profound truth that Nature does not know best; that genetical evolution All adaptations have a downside: horse legs are great for running on grass, but they can't scratch their backs; mammals ' hair helps temperature, but offers a niche for ectoparasites ; the only flying penguins do is under water.

Adaptations serving different functions may be mutually destructive. Compromise and makeshift occur widely, not perfection.

Selection pressures pull in different directions, and the adaptation that results is some kind of compromise. Since the phenotype as a whole is the target of selection, it is impossible to improve simultaneously all aspects of the phenotype to the same degree.

Consider the antlers of the Irish elk , often supposed to be far too large; in deer antler size has an allometric relationship to body size.

Obviously, antlers serve positively for defence against predators , and to score victories in the annual rut.

But they are costly in terms of resource. Their size during the last glacial period presumably depended on the relative gain and loss of reproductive capacity in the population of elks during that time.

Here the risk to life is counterbalanced by the necessity for reproduction. Stream-dwelling salamanders, such as Caucasian salamander or Gold-striped salamander have very slender, long bodies, perfectly adapted to life at the banks of fast small rivers and mountain brooks.

Elongated body protects their larvae from being washed out by current. However, elongated body increases risk of desiccation and decreases dispersal ability of the salamanders; it also negatively affects their fecundity.

As a result, fire salamander , less perfectly adapted to the mountain brook habitats, is in general more successful, have a higher fecundity and broader geographic range.

The peacock 's ornamental train grown anew in time for each mating season is a famous adaptation. It must reduce his maneuverability and flight, and is hugely conspicuous; also, its growth costs food resources.

Darwin's explanation of its advantage was in terms of sexual selection : "This depends on the advantage which certain individuals have over other individuals of the same sex and species, in exclusive relation to reproduction.

The most vital things in human life locomotion, speech just have to wait while the brain grows and matures. That is the result of the birth compromise.

Much of the problem comes from our upright bipedal stance, without which our pelvis could be shaped more suitably for birth. Neanderthals had a similar problem.

As another example, the long neck of a giraffe brings benefits but at a cost. The cost is that a long neck is heavy and adds to the animal's body mass, requiring additional energy to build the neck and to carry its weight around.

Pre-adaptation occurs when a population has characteristics which by chance are suited for a set of conditions not previously experienced.

With the Doughboy in France Edward Hungerford. The acquisition of modifications in an organism that enable it to adjust to life in a new environment.

The fitting, condensing, or contouring of a restorative dental material to a tooth or cast. The dynamic process in which the behavior and physiological mechanisms of an individual continually change to adjust to variations in living conditions.

Published by Houghton Mifflin Company. A change in structure, function, or behavior by which a species or individual improves its chance of survival in a specific environment.

Adaptations develop as the result of natural selection operating on random genetic variations that are capable of being passed from one generation to the next.

Variations that prove advantageous will tend to spread throughout the population. A Closer Look The gazelle is extremely fast, and the cheetah is even faster.

These traits are adaptations -characteristics or behaviors that give an organism an edge in the struggle for survival.

Darwinian theory holds that adaptations are the result of a two-stage process: random variation and natural selection.

A classic example is shown by the melanistic dark phenotype of the peppered moth Biston betularia , which increased in numbers in Britain following the Industrial Revolution as dark-coloured moths appeared cryptic against soot-darkened trees and escaped predation by birds.

The process of adaptation occurs through an eventual change in the gene frequency relative to advantages conferred by a particular characteristic, as with the coloration of wings in the moths.

The third and more popular view of adaptation is in regard to the form of a feature that has evolved by natural selection for a specific function.

Examples include the long necks of giraffes for feeding in the tops of trees, the streamlined bodies of aquatic fish and mammals , the light bones of flying birds and mammals, and the long daggerlike canine teeth of carnivores.

All biologists agree that organismal traits commonly reflect adaptations. However, much disagreement has arisen over the role of history and constraint in the appearance of traits as well as the best methodology for showing that a trait is truly an adaptation.

A trait may be a function of history rather than adaptation. The ancestors of giant pandas and all closely related species, such as black bears , raccoons , and red pandas , also have sesamoid bones, though the latter species do not feed on bamboo or use the bone for feeding behaviour.

Therefore, this bone is not an adaptation for bamboo feeding. The English naturalist Charles Darwin , in On the Origin of Species by Means of Natural Selection , recognized the problem of determining whether a feature evolved for the function it currently serves:.

The sutures of the skulls of young mammals have been advanced as a beautiful adaptation for aiding parturition [birth], and no doubt they facilitate , or may be indispensable for this act; but as sutures occur in the skulls of young birds and reptiles , which only have to escape from a broken egg, we may infer that this structure has arisen from the laws of growth, and has been taken advantage of in the parturition of the higher animals.

Thus, before explaining that a trait is an adaptation, it is necessary to identify whether it is also shown in ancestors and therefore may have evolved historically for different functions from those that it now serves.

Another problem in designating a trait as an adaptation is that the trait may be a necessary consequence, or constraint, of physics or chemistry.

One of the most common forms of constraint involves the function of anatomical traits that differ in size. For example, canine teeth are larger in carnivores than in herbivores.

This difference in size is often explained as an adaptation for predation. However, the size of canine teeth is also related to overall body size such scaling is known as allometry , as shown by large carnivores such as leopards that have bigger canines than do small carnivores such as weasels.

Thus, differences in many animal and plant characteristics, such as the sizes of young, duration of developmental periods e. Adaptive explanations in biology are difficult to test because they include many traits and require different methodologies.

Experimental approaches are important for showing that any small variability, as in many physiological or behavioral differences, is an adaptation.

The most rigorous methods are those that combine experimental approaches with information from natural settings—for example, in showing that the beaks of different species of Galapagos finch are shaped differently because they are adapted to feed on seeds of different sizes.

The comparative method , using comparisons across species that have evolved independently, is an effective means for studying historical and physical constraints.

This approach involves using statistical methods to account for differences in size allometry and evolutionary trees phylogenies for tracing trait evolution among lineages.
