The formation of new and distinct species.
What is speciation?
T or F: Dinosaurs are common ancestors of birds
True
This type of isolation: When two populations that can interbreed develop differences in courtship rituals.
What is behavioral isolation?
This is the "blueprint" of life.
What is DNA?
A group of living things that can interbreed and produce fertile offspring.
What is a species? (Biological definition)
Organisms not closely related evolve similar traits as a result of having to adapt to similar environments. EX) dolphins and sharks, not closely related, but both have fins.
What is convergent evolution?
This type of isolation: When two populations of a species are separated by a physical barrier, such as a mountain, river, or cliff.
What is geographic isolation?
Name all the traits on this chart that a bird has.
What is:
vertebrae
bony skeleton
four limbs
amniotic eggs
egg with shells
A chart showing how species are related, includes traits of each of the species, or groups of species. These are typically not length of time specific. + These charts are hypothetical
What is a cladogram?
Differences between closely related species adding up, leading to speciation. Ex) the variety of big cat species.
What is divergent evolution?
This type of isolation: When two or more species reproduce at different times.
What is temporal isolation?
In a phylogenetic tree or cladogram, these are the "trunks" before species split off.
What are common ancestors?
A chart showing how species are related. Typically these have lines that vary in length to show different amounts of time between separation of species. These charts are backed by DNA evidence.
What is a phylogenetic tree?
Name two ways speciation happens. (In general terms, not examples)
What is one species splitting and becoming two or a change in one species over time?
The eastern meadowlark sings a different song that the western meadowlark. Each species is only attracted to the song of their own species. This type of isolation.
What is behavioral isolation?
Where would you put the "hair/fur" trait?

C
A group of organisms and their common ancestors.
What is a clade?
Are a horse and a donkey (that can make a baby mule, who is sterile) the same species? Explain why or why not with evidence.
No because the mule cannot have offspring.
The general term for when a population splits into two groups so that those two groups no longer interbreed. Can be due to a variety of factors.
What is reproductive isolation?
How a phylogenic tree shows that a species is extinct.
What are no more descendants/branches?
