Mutations are important because they bring about

• death of the organism in which they develop
• genetic variation needed for a population to evolve
• benefits for the individual, not for the population
• Hardey-Weinberg equilibrium within a population

What is the process in which humans breed organisms for certain traits?

• natural selection
• inheritance
• artificial selection
• descent withOUT modification

Choose which scientist corresponds best with the statement: 
acquired characteristics are inherited

• Darwin 
• Lamarck

What type of evidence is shown in this picture?

• Fossils

• Homologous Structures

• Vestigial Structures

• DNA

Adaptations are:

• physical or behavioral tendencies.

• physical or behavioral characteristics that help an organisms survive and reproduce.

• physical or behavioral characteristics that do not help the organism in any way.

• genetic mutations that have gone wrong.
