Document Summary
Chapter four review questions: explain the premises and logic that support the concept of natural selection, the premises for natural selection is that organisms face a constant struggle to survive and reproduce, tend to produce more offspring then will survive, and individuals of a species vary in their characteristics. If the mutation leads to a trait that gives that individual an advantage, that individual is more likely to survive long enough to reproduce successfully and pass on the advantageous trait to its offspring through its dna: name two examples of evidence for selection, studies have been done to prove selection in species that reproduce fast (so evolution happens faster and can be monitored in lab. Selection has been proven through artificial selection, the human manipulation of desirable traits in pets, livestock, and crops: how does allopatric speciation occur, allopatric speciation occurs when a population of organisms is physically divided over some geographic distance, isolated from each other.
