homologous structure
What is structures that have different mature forms in different organisms but develop from the same embryonic tissues
100
evidence for evolution
What is
can be found in fossil records, geographical distribution, homologous structures, similarities in early development
100
principle that all living things have a common ancestor
What is common decent

what is natural selection
What is Darwin's theory which says that organisms best adapted to their environment are more likely to survive and pass on their traits to their offspring
200
Jean-Baptiste Lamarck
he proposed that by selective use or disuse of organs, organisms could acquire or lose certain traits which are then passed on to their children and future generations, eventually changing the species
200

competition among members of a species for food, living space, and other necessities of life
What is struggle for existence

Alfred Russel Wallace
What is
a naturalist who had the same thoughts on evolutionary change as Darwin
400
Analogous Structures
What is Structures that have become similar by performing the same function (convergent evolution)
400
inherited characteristic that increases an organism's chance of survival
What is adaptation
400
a well supported testable explanation of phenomena that have occurred in the natural world
What is theory
500
evolution
What is Changes over time that occur in the traits of a species.
500

Comparative Anatomy
What is Comparative Anatomy
500
group of similar organisms that can breed and produce fertile offspring
What is species
500
process through which early prokaryotic cells are thought to have engulfed other, smaller cells and eventually incorporated them as organelles (such as mitochondria and chloroplasts); these cells evolved into modern-day eukaryotes.
