2) Why do you think hormone cascades were selected for evolution?

Hardy and Weinberg (one a genetics expert and the other a mathematician) independently demonstrated that the alleles within populations may be stable under certain conditions. If the allele frequency is variable, they will change, and evolution is possible. If the allele frequencies are stable, will evolution be possible? THINK about this... by definition, evolution will NOT occur when the allele frequencies are stable.

1) What are the assumptions for STABLE allele frequencies for a population from one generation to the next?

2) Next, what occurs if any of these assumptions do not hold true (another words...the assumption do NOT apply)?

3) From the list of assumptions, select one (only ONE) and describe how it may/may not apply to a ‘natural population’ (this where things get very cool...)
