Mutation - permanent change to DNA or RNA (can be +, -, or neutral)
2. Gene Pool - all the different gene alleles in one species
3. Natural Selection- living organisms whose difference is an advantage are ‘picked’ by nature as more likely to survive and reproduce in an environment.
4. Adaptation - a change that is beneficial that happens over many generations
5. Adaption- a change that one individual makes, not genetic
6. Niche - a unique position held by one species (or a person) - where and how it makes its living better than others
7. Evolution = mutations + natural selection (+reproduction); over many generations
8. Micro-evolution -small scale - within a species
9. Macro-evolution - large scale - theoretically can account for all life forms from one
10. Speciation - evolving long enough to be different enough to make a new species
11. Homologous structures - structures that are the same in different species, like finger bones.
12. Evidence of theory of macroevolution -
a. Fossils (there were life forms that no longer exist, but they seem related)
b. Homologous structures (likely that organisms evolved from each other, that’s why they have similar organs, etc.)
c. Many different species have the same early developmental stages (Ontology recapitulates phylogeny ~ the evolution of species is replayed in the development of one individual
d. DNA similarities
13. Classification of species
a. D domain duh
b. K kingdom kind
c. P phylum Philip
d. C class comes
e. O order over
f. F family for
g. G genus good
h. S species soup
14. Binomial nomenclature = 2-name name, Genus, Species
15. Mass Extinction - 5 so far, MANY species gone in same period
