1 Theory of Evolution By Jordan Bel-Kane, Benny McMullen, Ambar Hernandez, & Tyler Berkemeier

2 Evolution Change in inherited traits from generation-to-generation
Driven by natural selection, and genetic drift Natural Selection – favorable traits are kept over unfavorable Genetic Drift – group of random changes in gene pool

3 Micro Evolution Micro evolution- change at or below species level
An example of microevolution is bacteria becoming resistant to antibiotics. Salmonella typhimurium invading cultured human cells.

4 Imperfection of Adaptation
Panda’s thumb more like bone than digit Animal’s are never perfectly suited for environment The panda thumb proves this It isn’t a digit-extra bone

5 Focus on changes at or above species level
Macro Evolution Focus on changes at or above species level Basically is the larger evolutionary changes The white moth is the original species, and the black moth micro evolved to better survive in a different environment.

6 Peppered Moths Peppered Moth Black Peppered Moth The white peppered moth began to macro evolve during the British Industrial Revolution To deal with rising pollution The black peppered moth was the offshoot species from the Peppered Moth to do deal with pollution

7 Theory of Evolution Evolution – widely accepted theory that organism’s are always changing All life struggles to survive and reproduce Struggle for survival weeds out weaker specimens Evolution takes so long, unobservable in a lifetime Based on random genetic mutations
