Evolution
This "father" of evolutionary theory.
Who is Charles Darwin?
Survival of the fittest is also known as . . . .
What is Natural Selection?
The process when one species splits off into multiple species.
What is speciation?
The movement of individuals into/out of a population, increasing genetic diversity.
What is immigration/emigration?
In its most simplest terms, what is evolution?
What is a change in species over time.
Large male lobsters get most of the females to breed with. The tiny males sneak in and breed as well. The medium males cannot do either, so they tend to miss out on breeding. What type of selection is this? (Stabilizing, Disruptive, or Directional)
What is disruptive selection?
The search for the "missing link" specimens that show the evolutionary transition between species.
What is fossil record?
Where did Darwin make his groundbreaking discoveries with the tortoises and finches?
Where are the Galapagos Islands.
Biologically speaking, this is the ability of an organism to survive AND reproduce young.
What is fitness?
Two species of birds are isolated from each other because they build different types of nests and they don't find each other attractive. What type of isolation is this? (Geographic, Behavioral, or Temporal)
What is behavioral isolation.
A random change in DNA that helps cause evolution.
What is a mutation?
All individuals are born with different DNA; some will survive better than others.
What is Genetic Variation?
Random events (weather, natural disaster, etc.) that kill off enough individuals and isolate a small segment of a population, forcing them to start their new population with a small gene pool.
What is a genetic bottleneck?
Red foxes live near the city, while gray foxes live out in the countryside, so the two species never cross paths. What type of isolation is this? (Geographic, Behavioral, or Temporal)
What is geographic isolation?
Two organisms share a large amount of genetic material, indicating they are probably related.
What is DNA comparison?
The choosing of mates with a particular set of traits that make them attractive.
What is sexual selection/nonrandom mating?
Evolution is a change in the gene pool over time; what is that shift in gene percentages called?
What is allele frequency?
A small group of individuals leave the main population, and as a result, their new population has a very limited gene pool. (Hint: Amish)
What is Founder's Effect.
Hippos with tusks that are too small are outcompeted by bigger males, while those with massive tusks may suffer health issues. Therefore, the medium-length tusks fare the best. What pattern of selection is this (Disruptive, Stabilizing, or Directional)
What is stabilizing selection?
What is embryology?
What is the name of the mathematical theory that looks at the allele frequencies in a population? AND what are the 2 formulas that are used for it?
What is Hardy-Weinberg Theorem
p + q= 1 p2 + 2pq + q2= 1
