15.A.1 Natural selection

“I like guys who are well mannered, funny…” Miley starts.

“Okay, so that’s personality, but looks?” Jeremy reiterates.

“Tall, dark and handsome guys…” Miley continues.

“Like me,” Jeremy laughs, “but you get the idea.”

“If I, for instance, have kids with a blonde, my kids are going to turn out different from if I married a brunette,” Jeremy said.

“Exception, of course being Hannah Montana and Miley Stewart,” Miley replied, “since they are one in the same.”

“Yep,” Jeremy responded.

15.A.1.a fitness concept

So let’s talk evolution, Miley.

The gene pool is the total of all alleles in a population.

Evolution is a change in that gene pool.
