What are Homologous structures

One very important mechanism for evolution is genetic drift, which is the
What is changes in the allele frequency of a population due to random events.

What is he explained that populations grow faster than resources. This lead Darwin to his "struggle to survive" idea.

What is geographic isolation

A farmer only grew one type of soy bean plant. All of her soy bean plants died from the same disease. What was most likely true of the soybean plant population? a.They had a lot of resistance to disease b.They had a few plants that were resistant to the disease c.They had too much variation in their genes d.They had little variation in their genes
What is d.They had little variation in their genes

The body parts of organisms that do not have a common evolutionary origin but are similar in function are called
What are analogous structures?

Explain how gene flow can change allele frequencies in a population overtime.
Gene flow is the exchange of genetic information between populations. It can increase genetic diversity.

Humans have an appendix, a thin tube connected to the large intestine that serves no purpose and is a threat to human health and life if it becomes infected and/or inflamed. It is believed that the appendix once had a function as part of the human digestive system. The human appendix, therefore, is a _____.
