Describe how natural selection occurs?
Natural selection is the means by which living things are selected to reproduce. It is called natural because it is what happens in what is considered ordinary living conditions. It works by allowing only those creature capable of surviving getting to reproduce. If a creature is incapable of living/surviving in the environment that it finds itself in then it doesn't reproduce and becomes extinct.
What is the difference between natural selection and adaptations?
NATURAL SELECTION --The process in nature by which, according to Darwin's theory of evolution ,the organisms best adapted to their environment tend to survive and transmit their genetic characteristics in increasing numbers to succeeding generations while those less adapted tend to be eliminated.ADAPTATION--In biology, the process by which an animal or plant becomes fitted to its environment. It is the result of Natural selection acting on inherited variation. Even simple organisms must be adapted in many ways, including structure, physiology, and genetics; movement or dispersal; means of defense and attack; and reproduction and development. To be useful, adaptations must often occur simultaneously in different parts of the body.
What two limits to evolution by natural selection?
Natural selection is limited by the ability of the population to produce variation. This in turn is limited by the amount of mutation a lineage can survive. Too many mutations, and the effect becomes detrimental. Too few, and the population may not be able to adapt fast enough to changing circumstances and go extinct.
Artificial and natural selection?
Artificial selection is when a human determines how an animal or plant breeds. For example: dog breeding. A breeder will put a male and female dog of the same breed together while the female is in heat in order to get them to breed. S/he chooses a male and female biased on their looks, genetics, and temperament. Natural selection however is when nature determines how an animal breeds. For example: wolves. If the temperature drops below a level which wolves with a thinner coat cannot survive, then they will die and thicker coated wolves survive and breed, resulting in wolf pups with thicker coats.
Is the population bottleneck an example of natural selection?
No. Population bottleneck refers to a period in which the size of a population becomes much reduced, thereby reducing the number of alleles in the gene pool - and thus genetic diversity.
What is the process by which a species becomes better suited to its environment called?
Sometimes this is called natural selection.
How is natural selection at work when a species becomes extinct?
Natural selection occurs when a certain environment favors a particular characteristic or trait over another. With this being said, when a species becomes extinct, this means that that species' particular set of characteristics or traits was not the most favorable for them to survive in that certain environment.
When part of a population becomes separated from the rest what often begins?
Natural selection
A change in an organism's environment that causes the organism to react is called?
The change is actually a stimulus and when the organism reacts to the stimulus, it becomes a response. Overall, The answer is a stimulus.

Explain how natural selection is at work when a species becomes extinct?
According to science, natural selection chooses the best features for the best survival. When those processes do not occur for some reason, the species does not survive.

How did looking at fossils help Darwin form his theory of natural selection?
Evolution refers to the process of the collection of genes in variety and in frequency changing from one generation to another by reason of selective factors (i.e. natural selection, artificial selection, sexual selection, etc.). Some misinterpret this to mean that one species always becomes a new species which may happen but generally, the changes that happen are slight and go unnoticed. Overtime though, a timeline of fossils reveals very interesting trends like humans possibly developing a straighter posture. In short, fossils can demonstrate new species forming from old ones, adaptations in response to the environment, or what have you.
Why is darwin's theory of natural selection referred to as gradualism?
because the theory states that life gradually becomes more complex.
What is naturl selection and how does it relate to evolution?
Natural selection is where an animal changes over a period of time to adapt to it's environment. For example a giraffe might not have a long enough neck to reach the top leaves on a tree so over many generations the neck becomes longer and longer until it can reach those leaves. This ties in with evolution because the giraffe is evolving to cope with it's environment.
