Evolution Basics
This scientist proposed the theory of natural selection
Who is Charles Darwin?
Organisms with favorable trains are more likely to do this
What is survive and reproduce?
These structures have similar anatomy but different functions
What are homologous structures?
hardy-Weinberg predicts this if a population is not evolving
What are constant allele frequencies?
This is the formation of new species
What is speciation?
This is the change in the genetic makeup of a population over time
What is evolution?
Traits that improve survival and reproduction
What are adaptions?
Similar embryos across species show this type of evidence
What is embryological evidence?
One condition for Hard-Weinberg
What is no migration, large populations, no natural selection?
When species are separated by physical barriers
What is geographic isolation?
This is the smallest unit that can evolve
What is a population?
The environment "selects" which traits are favorable in this process
What is natural selection?
These molecules are compared to show evolutionary relationships
What are DNA or protein sequences?
The equation for genotype frequency
What is p^2 + 2pq + q^2 = 1
These types of barriers prevent mating or fertilization
What are pre zygotic barriers?
The preserved remains of ancient organisms
What are fossils?
The process where humans breed organisms for desired traits
What is artificial selection?
Organisms with more of this in common are more closely related
What are genetic or molecular similarities?
This random event changes allele frequencies in small populations
What is genetic drift?
When species evolve from a common ancestor into many new forms
What is adaptive radiation?
A structure that is no longer used but shows evolutionary history
What is a vestigial structure?
Natural selection leads to changes in this measurable feature of traits in a population
What is allele frequency?
This technique estimates evolutionary relationships using DNA or protein data
What is phylogenetic analysis?
The bottleneck and founder effects are examples of this
What its genetic drift?
The sudden disappearance of many species
What is mass extinction?
