Individual animals do not adapt.
Adaptation happens over generations within a species in a certain environment.

How would you use evolution natural selection adaptation and fitness in a sentence?
An important mechanism in evolution is natural selection, which allows populations to develop adaptations to changing circumstances based on the fitness landscape of the environment. Nah, still doesn't work. I'm no good at long sentences.
How hummingbird came to have long tongues because of natural selection?
No, it is an adaption. To be more accurate it is a Structural Adaptation. Structural adaptations are adaptations that contributes to the survival of the organism. For example the arctic fox has thick coated fur to help keep warm.hope this helped : )
What was in the Darwin's book the Origin of Species?
One long argument with supporting evidence for the theory of evolution by natural selection. Starting with artificial selection, used as an analogue for natural selection, and ending with the distribution of animals, biogeography, Darwin showed the species arose through natural process over long lengths of time.
How is darwins theory of evolution by natural selection related to the origin of structural and physiological adaptations?
Natural selection "filters out" and selects the best or most energy efficient structures. It's a optimisation process geared towards what survives long enough to leave the most amount of viable descendants, that themselves will live long enough to produce more and so one.However, since mecanisms in modern creatures go back a long way in time, it can be the case that they are not perfectly optimal or simply that they are "piggy-backing" on something that has been selected. Evolution tries to prime and adapt what it's got, animals don't start off with whole new blueprints after wiping a species' genetic history clean.Random mutations do cause new genes and possible adaptations to occur though.
Did the theory of natural selection come before heliocentric theory?
No. Not by a long shot.
What resulted from a genetic variation that was favored by natural selection?
the long neck of a giraffe
What was natural selection based on during the holocaust?
The Holocaust has nothing to do with natural selection, or vice versa. The Holocaust was the result of atrocious crimes committed under the leadership of a few madmen, inspired by a long tradition of antisemitism. Natural selection is a model that describes differential reproductive success in natural populations, under natural circumstances.
Example of how natural selection occurs?
Lets say you have two bunnies. One has a long tail, the other has short tail. The one with the long tail died because a predator was able to catch onto the long tail and eat it. Therefore, the long tailed bunny can't pass on the characteristic of a long tail and that trait is no longer seen in bunnies. However, the bunny with the short tail isn't caught by predators as easily, and as a result, passes on the trait of a short tail to its offspring. After a long amount of time, no bunnies will have long tails because all the bunnies with long tails were killed out, and as a result, can't pass on the characteristic of a long tail. Bunnies then evolve to always have short tails.
Which of the following resulted from a genetic variation that was favored by natural selection?
The Long Neck of a Giraffe .
What does natural selection over long periods of time lead to?
Natural selection over long periods of time leads to a fitter and more reproductively successful group of organisms thus becoming more common in a population. It will lead to evolution.
Which type of selection can result in branching evolution if it goes on long enough?
Natural selection is the type of selection that can result in a branching evolutionary tree if it goes on long enough. This is because organisms may eventually evolve into a distinct species.
How long after an earthquake does nausea occur?
There is no requirement for nausea to occur due to an earthquake or any other natural phenomenon.
