The struggle for existence was proposed by this man.
Who is (Thomas) Malthus.
200
Genetically speaking, if evolution takes place, THIS is what changes within a population.
What is allele frequency (or gene pool)
200

What is igneous rock
200
A speciation event is represented by ___ on a cladogram.
What is a node
300
Term: Humans choose traits they find beneficial for an organism and then breed for those traits so that the trait is more pronounced in the next generation.
What is artificial selection Ex. selecting for traits in pets, crops, etc.
300
Natural selection for an intermediate phenotype is called this.
What is stabilizing selection. Example: An intermediate birth weight is more fit than a large or small weight.
300
Using fossils found in similar rock layers to say organism A was older than organism B is called ____.
What is relative dating
300
The dinosaurs became extinct at the end of this era.
What is Mesozoic
400
List 3 (of the 5) evidences for evolution
biogeography, homologous structures (comparing anatomy), tests for natural selection (Grants' study), fossil record, genetic and molecular evidence (compare DNA)
400
Two examples of genetic drift
What are bottleneck effect and founder effect.
400
The rate of evolution in which periods of steady change are interrupted by abrupt periods of rapid change.
What is punctuated equilibrium.
400
What do scientists believe occurred after aerobic prokaryotes?
What are eukaryotes.
500
3 parts of natural selection
struggle for existence variation and adaptation survival of the fittest.
500
Speciation requires this characteristic _____. AND, it can happen by these 3 ways: _______.
Necessary: reproductive isolation. Can result from:behavioral isolation, geographic isolation OR temporal isolation
500
BONUS (not as hard on test): A sample is found to contain 20g Argon-40, and 60g of Potassium-40. Assuming that Potassium-40 decays into Argon-40 with a half-life of 1.3 billion years...how old is the sample?
What is 650 million. 1/2 of a half life has occurred (20+60 = 80g of Potassium-40 originally --> if 1 half life occurred, then 40g would be Argon-40 but only 20g has formed, therefore, 1/2 of a half life = 1/2 of 1.3billion)
500
