Mechanisms of Evolution Chpt 6-1 Is evolution a Theory? Why is it Controversial?
Speciation Discussion How does a new species arise?
15.3 NOTES. Genetic Drift A random change in the frequency of an allele in a population NOT due to natural selection. More likely to occur in small populations.
Aim: How did species evolve ? HW 13 Text read chapter 16 Do Analyzing Data Activity page 408.
Chapter 15 Evolution. Think About It? What is evolution? What is evolution? Why does it happen? Why does it happen? How does it happen? How does it happen?
Changes over time Life originated from a single-celled organism. Finding a fossils age helps scientists to construct an evolutionary timeline.
