Notes Packet pg. 19
2 types of populations in evolution.
- Non evolving
Micro Evolution - Evolution on a small scale
Here is a example of evolving populations in slight combination with micro evolution
(we all know Darwin loved his Finches)
This concept is well explained in the video below.
Two types of genetic drift.
- The Founder Effect
Both of these terms are explained very clearly, and with good detail in this video.
Gene Flow :the continuation of Micro Evolution
Gene Flow - a population may gain or loose alleles by genetic exchange with another population.
The details of gene flow are explained well in the video below.
Mutations - change in an organisms DNA
Natural Selection - a blend of chance and sorting
- Those that work best in the environment leave the most offspring and have a disproportionate impact on the gene pool.
The flowing video explains the principals of natural selection
Only watch 2:10 to 3:45 (the rest is an argument with creationist theorists)
