all of them

Which of these are used as evidence for evolution: fossils and the fossil record, biogeography, comparative anatomy, comparative embryology, molecular biology?

Evolution can be defined as ____.

change over time

adaption

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

Biogeography

species are found in certain areas because their ancestors lived in the area also

adaptive radiation

the rapid formation of lots of species from one common ancestor

molecular biology

the study of biological structures, functions and heredity

comparative embryology

the study of the similarities and differences in the embryos of different species

continental drift
