what are the forces of Evolution? Why is it called that? Please Explain!
Answers
Answer:
Explanation:The four forces of evolution are: mutation, gene flow, genetic drift, and natural selection. Mutation is a random heritable change in a gene or chromosome, resulting from additions, deletions, or substitutions of nitrogen bases in the DNA sequence.The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits.
Answer:
bottleneck effect Genetic drift that occurs when a population suddenly gets much smaller.
founder effect Genetic drift that occurs when a few individuals start, or found, a new population.
gene flow Change in allele frequencies that occurs when individuals move into or out of a population.
genetic drift A random change in allele frequencies that occurs in a small population.
