natural selection 4

organisms produce more offspring than can survive

• taxonomy

• phentotype

• variation

• overproduction

structure similar to a fish gill on the neck of an embryo; these develop into ears and jaw structures in humans

• homologous structure

• pharyngeal pouch (arch)

• vestigial structure

• analogous structure
