Evolution Vocabulary

2. Genetic changes within a population over many generations show evolution shapes life
7. Geographic barriers divide populations, creating a new allopatric sepeciation
10. mutual species co-evolution drives that reciprocal adaptions
11. Trace fossil evidence includes preserved footprints, burrows, or ancient biological activated
12. Random events genetic drift change allele frequencies
14. A close relationship where symbiosis involves two different species living together
15. beneficial traits adaption allows species to survive harsh environments
16. Congruent species independently develop similar features
17. Study embryology to understand how organisms develop initially
18. Widespread organisms used as index fossil date rock layers
19. The process by which speciation occurs involves populations becoming distinct and repreductively isolated
20. Species avoid temporal isolation by breeding during different seasons or times
21. Traits from separate lineages considered analogous evolved for similar functions without ancestry

1. Barriers geographical isolation physically separate distinct populations
3. Survival and reproduction through natural selection ensures that favorable traits persist over generations
4. new species evolve through sympatric speciation while living together within habits
5. Diverse species quickly evolve because adaptive radiation allows them to fill many niches
6. features homologous are shared structures inherited from a common ancestor
8. Barriers that prevent breeding reproductive isolation ensure species remain genetically distinct and seperate
9. The scientist who proposed that species change over time through Darwin natural selection was essential
13. Species split to become divergent forms
