Theory
What did Darwin believe?
Organisms change over time, and living things with beneficial traits produce more offspring.
What is a Paleontologist?
Scientist who studies fossils
Microevolution
Short period of time
Sympatric Speciation
New speciation without geographic seperation
Why is it used?
It serves as a hypothesis in population genetics to determine if a population is evolving or not
What did Charles Lyell figure out?
Earth is much older than people thought
What is comparative anatomy?
It is the study of similarities and differences in structures of different species
Genetic Drift
Random changes that happen in a small population
Coevolution
Species in symbiotic relationships tend to evolve together
No mutation, random mating, no gene flow, very large population size
Who was Thomas Matthus?
English Economist
Similar structures inherited from a common ancestor
Gene flow
Individuals move in and out of gene pool
Gradualism
How is it done?
By verifying the allele and genotype frequencies remain constant
Do continents and oceans change dramatically overtime?
Yes
What is a Analogous structure?
Structures that are similar in unrelated organisms
Allele Frequency
Shows how many of each allele is found in the population
Punctioted Equilibrium
Conditions are changing evolution happens more quickly and is better supported in the fossil record
Why is it unlikely in real life?
It requires strict conditions which natural wildlife are just not going to follow.
What is artificial selection?
Humans can breed plants and animals to create more useful traits.
What is Comparative Embryology?
Study of similarities and differences in embryo of different species
Alleles in a population don't change if,
There are no mutations, no migration, very large population, mating is random, and there is no natural selection
Geographic seperation which doesn't allow species to interbreed
Who does Hardy-Weinburg refer to?
A mathematicion and physician who founded the principle
