What is the five processes of microevolution?

Answer 1

The factors that help determine the course and direction of evolution by natural selection are many: predation and disease, migration and conflict, behavior and temperament, competition for breeding space and mates, and competition for living space and food. Purely physical factors in the environment are no less important: stability or instability of the climate; solar radiation; natural disaster; pollution of the soil, water, and air-all will have their effect and take their toll on living groups.

Answer 2

The five recognized causes of biological evolution are as follows:

1. mutation

2. migration also known as gene flow

3. random genetic drift (small populations)

4. non-random mating

5. natural selection

*this is the correct order

Answer 3

This is not correct: nonrandom mating, mutation, migration, genetic drift and natural selection.

Seriously, this is the answer that's posted here? The basics for evolution are three conditions.

1. VCR is the best way to remember it. Variation (as in genetic), Competition (for survival) and Reproduction (to pass on certain advantageous traits).
2. Natural selection is merely the method in which evolution takes place, not a condition for it.
3. Non-random mating is a more detailed aspect of the reproduction portion. It is necessary for the passage of specific traits.
4. Mutation is basically genetic variation. Without the variation, there are no advantageous traits to evolve with.
5. Migration and genetic drift allow different types of natural selection to occur within a species because of a change in the competitive environment. Different traits become advantageous because the environment is different. It's what allows the same type of organisms to look different (i.e. different length beaks in birds of the same species.)

Answer 4

Changing climate, predators, habitat loss, primary foods genetically change (becoming taller, harder to open etc.), and opportunity (finding a place with much easier ways of living and needing to adapt e.g. fish developing legs to maneuver in marsh where there's more food)

Answer 5

Evolution refers to the change in a species over a period of time. The five forces that cause evolution to occur in a population are: natural selection, gene flow, mutations, genetic drift and non-random mating.

Answer 6

gene flow , genetic drift , mutation , natural selection , sexual selection.

Answer 7

Natural Selection, Genetic Drift, Mutations, Recombination, and Gene Flow are the five processes that affect evolution.
