Macro and Micro Evolution

Part of the evidence of evolution has to do with similar physical features in organisms that share a common ancestor,  

• Homologous Structures 

• Vestigial Structures   

• Biodiversity

As the rabbit population grew in our simulation of natural selection, what would keep the rabbit population low?

•  Adding more food sources. 

•  Making food hard to find.  

•  Adding gene traits like better hearing and teeth.

What is the primary difference between macroevolution and microevolution?

• Macroevolution refers to changes within a species, while microevolution refers to changes that lead to new species.

• Macroevolution involves large-scale changes over long periods, while microevolution involves small-scale changes within a species.

• Macroevolution is the study of genetic drift, while microevolution is the study of natural selection.

• Macroevolution occurs at the molecular level, while microevolution occurs at the ecosystem level.

• The change in allele frequency of a population of moths due to industrial pollution.

• The extinction of dinosaurs.

• The formation of the Himalayas.
