Principles of Natural Selection
The measure for how well you can survive in your environment
What is fitness
Group of organisms that can successfully interbreed and produce viable, fertile offspring
What is a species
The unifying theme of biology
What is evolution
The field of biology that classifies organisms
What is taxonomy
Differences in physical traits of organisms
What is variation
What must occur for speciation to happen
What is isolation
Preserved remains of organisms that link ancestral species to their descendants
What are transitional fossils
The 2-name naming system, Genus species
What is binomial nomenclature
Movement of genes in/out of a population
What is gene flow
Occurs when a catastrophic event changes the environment suddenly, like a meteor hitting Earth
What is a mass extinction
A types of structure where it is similar structure, but different function, due to being used in different environments
When a prokaryote ends up inside of another and both organisms thrive
What is endosymbiosis
non-random mating
What is sexual selection
Slow, constant changes over a long period of time
A species that exist only in one geographic region
What is an endemic species
A diagram used to predict evolutionary relationship among groups of organisms
What is a phylogenetic tree
When there are NO changes in the allele frequencies in a population over time
What is Genetic equilibrium/Hardy-Weinberg equilibrium
When unrelated species evolve similar characteristics because they live in similar environments
What is convergent evolution
Nonfunctional genes that are like the vestigial structure of your DNA
What are pseudogenes
a common ancestor that all organisms on a tree evolved from
