definition of evolution
What is descent with modification?
2 types of fossil record (list) and description
Relative dating
Radiometric dating
only found in sedimentary rock
"measures and quantifies difference to create a timeline of change."
definition of molecular biology
measures/quantifies the differences in both DNA and/or proteins
inviable hybrid definition
What is a hybrid that is weak/dies before it can mate?
The three modes of natural selection
What are directional, disruptive/diversify, and stabilizing selection?
definition of extant
What is a species that is still alive today?
Comparative anatomy: homologous structures (definition)
same but not identical, supports divergent evolution
The way to write the name of one species using two parts of the taxa.
What is Genus species, e.g. Canus lupus
gametic barrier definition
What happens when the cells don't recognize each other and don't make a zygote?
The slower type of speciation event
What is allopatric speciation?
definition of species
What are organisms that can and will mate to produce a fertile offspring?
Comparative anatomy: analogous structures (definition)
evidence of convergent evolution: used/functions/looks the same but evolved differently.
A graphical representation of an organism's phylogeny.
What is a cladogram?
hybrid breakdown definition
The two types of speciation
What are allopatric and sympatric speciation?
definition of taxa
What is the attempt to organize living things into categories called?
Comparative anatomy: vestigial structures (definition)
Structures that are present but not used.
The four types of evidence for evolution
What are fossil record, comparative anatomy, comparative embryology, and molecular biology?

What are inviable hybrids, sterile hybrids, and hybrid breakdowns?
Evidence for a non-evolving population list
What are a large, varied population, an isolated population, no mutation, random mating, and equal reproductive success?
The new system that is based on evolution
What is modern classification?
definition of comparative embryology
measures/quantifies the similarities in developmental stages (differences in embryos)
