Evolution 1

heritable characteristic that increases an organism's ability to survive and reproduce in an environment

body parts that share common function, but not structure

selective breeding of plants and animals to promote the occurrence of traits

changed by organism during lifetime by using or not using a specific characteristic and then passed to offspring

change overtime; the process by which modern organisms have descended from ancient organisms

how well an organism can survive and reproduce in an organism

preserved remains of ancient organisms

structures that are similar in different species of common ancestors

process by which organisms that are most suited to their environment survive and reproduce most successfully; also called survival of the fittest

structure that is inherited from ancestors but has lost much or all of its original function

geologists that said the Earth is really old

biologist that proposed the theory of acquired traits as a means of evolution - organisms change during their lifetime and pass those changes on to their offspring
