Review: Evolution & Taxonomy

What is a mutation?

• It's when an organism adapts to its environment

• It's when the offspring of two parents is different from each parent

• It's when the genes mix to create a new combination

• It's when the DNA sequence changes due to a mistake when it divides during mitosis or meiosis

What are homologous structures?

• Structures that are only found in humans.

• Structures that are only found in plants.

• Structures that have no similarities and are found in different species.

• Similar structures found in different species that share a common ancestor.
