How does an organism evolve?

Answer 1

A species is often defined as a set of organisms that reproduce in nature. If members of the species change so much that they can no longer reproduce with the other members of the species, those members are considered to be a new species. As an example: If a species of birds becomes separated and over time one group's mating dance is two hops to the right and one to the left while the other group's dance is two hops to the left and one to the right. Those two groups will no longer be able to interbreed because the females won't be properly impressed if the dance is performed "wrong".

Answer 2

Plants evolve in much the same manner that all other organisms do. Through the process of natural selection. Features of the plant that allow the plant to better survive in the environment in which it is in will crowd other plants of the same species and eventually become the dominant genotype.

Answer 3

Organisms evolve through the process of natural selection, where individuals with genetic variations that are better suited to their environment are more likely to survive and reproduce. Over time, these advantageous traits become more common in the population, leading to evolution. Random mutations also contribute to genetic diversity and can drive evolutionary change.

Answer 4

They don't. There is proof against, not for evolution. Why don't we see a partially evolved elephant or such?

Answer 5

If a certain group of organisms survive predators or their environment for a period of time, their traits would change for the sake of their survival.

Answer 6

yes. They evolve just as animals do. Those who are able to survive the best pass on their genes.

Answer 7

Speciation only causes the production of varieties in specific organisms. Darwin's finches are a prime example...they are now differing but remain finches.
