1. speciation The process by which one species splits into two or more
species
- foundation of evolution
- bridges microevolution and macroevolution
2. microevolution changes in allele frequency in a population over time
3. macroevolution the broad pattern of evolution change above the species
level
the cumulative effect of many speciation and extinction
events
4. species a latin word
"kind or appearance"
5. biologists com- morphology
pare physiology
biochemistry
rRNA nucleotides
6. biological A group of populations whose members have the potential
species to interbreed in nature
- produce viable/ fertile offspring
- no successful breeding with other members
7. reproductive iso- a barrier between two species that keep them from pro-
lation ducing biological offspring (fertile, viable)
8. hybrids the offspring from mating two different species
9. isolation classifi- prezygotic barriers
cations postzygotic barriers
- classified whether factors act before or after fertilization
10. prezygotic barri- the reproductive isolation that blocks fertilization
ers
by keeping different species from mating

prevent successful completion of mating
and stopping fertilization if mating is successful
11. types of prezy- habiting isolation
gotic barriers temporal isolation
behavioral isolation
mechanical isolation
gametic isolation
12. habiting isolation when two species rarely or don't contact each other be-
cause they are not in the same reigon (no barriers)
13. temporal isola- when species breed at different times of the day, different
tion seasons, or years cannot mix gametes
14. behavioral isola- when there are different unique courtship dances and
tion sounds for a specific species, barriers to mating
15. mechanical iso- the morphological parts do not fit, therefore successful
lation mating cannot occur
16. gametic isolation the fertilization of sperm and eggs is not compatible be-
tween species; mating does not occur
17. postzygotic bar- prevent the hybrid zygote from developing into a viable,
riers fertile adult
18. types of postzy- reduce hybrid viability
gotic barriers reduce hybrid fertility
hybrid breakdown
19. reduce hybrid vi- the genes of the different parent species may interact and
ability impair the hybrids development or survival in the enviorn-
ment
20. reduce hybrid the hybrids are vigorous, but they are sterile
fertility
21. hybrid break- some of the first-generation may be fertile but every next
down mating makes the offspring weaker and weaker
