Father of Evolution, wrote Origin of Species and studied organisms from Galapagos to support his proposal that natural selection occurs

Siblings
Parents
gene flow
natural selection
bottleneck effect
founder effect
During a hurricane, a population of beetles almost gets completely wiped out. The only beetles that survived were lucky that they were in their nest at the time of the hurricane and had enough food to survive.
Natural selection
Genetic Drift
Gene Flow
Non-Random Mating
This term refers to the total genetic information found in a population; the complete collection of all the alleles found in a population
Gene library
Genome
Gene pool
Allele pool
Which best describes punctuated equilibrium?
Speciation occurs due to natural selection

Speciation occurs slowly in geologic time, followed by long periods with very fast evolutionary change.
Speciation occurs suddenly and rapidly in geologic time, followed by long periods with little evolutionary change.
The large-scale events of speciation are called...
macroevolution
simplification
adaptation
microevolution
During microevolution, a(n) __________________ will become more or less common within a population.
species
allele
ribosome

Speciation can occur as a result of geographic isolation because _________.
members of a species can no longer find mates
populations that live in different environments may be exposed to different selection pressures
exchange of genes during recombination
movement of genes within a population because of interbreeding
Which of these is a condition that must be met for Hardy-Weinberg equilibrium?
