EVOLUTION

1. similar structures but have different anatomies
8. the transfer of genetic material from one population to another
10. when a portion of a current population becomes isolated due to geographical barriers
12. drug used to treat infections caused by microorganisms and bacteria
13. the development of new species
14. species that have vestigial bind leg bones
15. the early stages of development of an organism
17. a population of organisms with similar genes
18. structures that are inherited that are often smaller and
19. when a specific number of species are separated from the rest of the group

2. occurs when there are no physical barriers preventing any members of a species from mating with another
3. structures that evolved from the same ancestral body parts
4. members of the group that later gave rise to the modern human being
5. a cell the develops into a reproductive cell
6. molecules that build and support body parts
7. when a population moves from its current habitat to a new one
9. species that are similar to a zebra
11. remains of an organism
15. any change in the genes of a population of organisms over a period of time
16. located in the chromosomes which consists of DNA
