D Question 22 8 pts What are three mechanisms of evolution described five in lecture Choose one mechanism and create a hypothetical scenario to describe how that specific mechanism would change the allele frequency over time for a population of rabbits. BIVA- HTML - Page . I Question 23 6 pts Magpot flies used to lay there only on apple trees, but recently some apple magot flies began to lay their eses on nearby oranges instead. Now there are two groups of poflies one that loves on apples and one that lay eggs on oranges. Males only look for mates on the same type of fruit that they grew up on. There are now genetic differences between the two groups and over a long period of time, they could become separate species What mode of speciation is occurring! Define the mode of speciation that is occurring and explain how ith applied in this example, HTML

Answer 1

22. Three mechanisms for evolution are :

1. Mutation

2. Genetic Drift

3. Natural selection

Mutation:

If the genes of the rabbit mutates in a way that leads to a decrease in the size of its ears but increase the efficiency of hearing, then the rabbit over time will develop ears that are smaler in size but can hear more efficiently.
