How does a gene pool relate to evolution?

Answer 1

Mutations of DNA can cause different characteristics to what you might consider "standard" for a particular species - This is genetics and it happens all the time. If the environment in which a particular species lives changes then a certain mutation may become beneficial. The organisms with this mutation then become better adapted to live in the new conditions than the other organisms. The unmutated organisms may then begin to die out while the mutated organisms survive. These mutated organisms, over time, become the majority through breeding and the passing on of this beneficial mutation of DNA. This is evolution.

Example:

What we now know as the Horse originally had cloven feet (sort of like a camel's foot but more hand like!) which was perfectly adapted to the boggy terrain on which they lived. As the Earth began to dry out, the terrain became less and less boggy. A mutation caused some of the "Horses" to have fewer extremities (their feet were slightly more hoof-like) and they were now better adapted to the surroundings and were able to travel much faster over the drier land and escape predators. This mutation then gets passed on through breeding as the cloven footed "Horses" began to die out. Successive mutations over thousands of years resulted in the hoof and the Horse that we recognise today.

Answer 2

Very broad & debatable topic.. This has alot to do with Charles Darwin's theory of evolution & the mechanism of natural selection. Of course, it's more Neodarwinism since there was no knowledge of Genes or DNA at the time he had come up with his theories.. The concepts still apply though. I could write a novel right here for you just rambling on about it, but there are plenty sites to choose from.

Answer 3

Natural selection is when one organism in its species population chooses to mate with another organism in that species population because it is more fit for that environment. for example: in a population of giraffes, as food is deplenished the giraffes with taller necks can reach the tops of the trees to get the uneaten leaves. therefore they are more fit for the environment and will be mated with whereas the ones with shorter necks will die off because they cannot reach the leaves for food. now the giraffes with taller necks will add that gene to the gene pool of their population and pass on their genes to the next generation. This is how animals evolve. as environmental conditions change, so does the gene pool of the population, and this changes the genotypes and phenotypes of the population therefore changing the species itself.

Answer 4

Evolution is the change in allele ( different molecular forms of the same gene ) frequency over time in a population of organisms.

Yes, genes are in this genetic definition of evolution. Natural selection selects from variant organisms and those variations that have better survivability and reproductive success pass on the genes that control/influence these traits to their progeny and that, over time in the population, is evolution.

Answer 5

A gene pool refers to all the different genes present in a population. Evolution occurs as genes in a population change over time through processes like natural selection, genetic drift, and gene flow. A diverse gene pool allows for variation, which is essential for a population to adapt to changing environments and drive evolution.

Answer 6

Genes make up any living creature. Evolution is the change or mutation in genes, that make things different years down the line.

Answer 7

Everything. Genes are where change can even be made!

Answer 8

because once a gene is taken out from the gene pool, the gene doesn't exist anymore at all. so that gene can not be passed on. so now there wont be any species with that characteristic.

Answer 9

Because they are
