5. a speciation occurs when there is a ecological barrier separating populations
8. a speciation occurs when there is physical barrier between populations
11. is evolution on a large scale
12. a type of mimicry when a venomous species resembles one another
14. is the change in groups of organisms over time
15. is the role that an organism has in it’s environment

1. adaptations that organisms do to help them survive or reproduce
2. a structural adaption that enables species to blend in with their surroundings
3. adaptations that are changes in an organisms metabolic processes
4. is the idea that evolution occurs slowly due to the accumulation of small changes
6. is evolution on a small scale
7. a type of mimicry when a non-poisonous species resembles a poisonous species
9. is the theory that evolution occurs during rapid “jumps”
10. is a measure of their contribution to the gene pool of the next generation
13. adaptations that are physical features of organisms
