3 requirements for evolution? - Answer-Variation in a trait, Heritability of the trait, and
Selection based by the trait.
The 3 types of natural selection? - Answer-directional, stabilizing, disruptive
What is directional selection? - Answer-selection which occurs when a phenotype at
one extreme is at a disadvantage. Favors one trait
What is stabilizing selection? - Answer-favors intermediate phenotypes
What is disruptive selection? - Answer-favors individuals at both extremes of the
phenotypic range
What is Crypsis? - Answer-the species has select characteristics that make them
blend in with there environment
What is Aposematism? - Answer-the species has characteristics that show "warning"
and make sure others know of them
Rules for naming a species? - Answer-- may us generic name w/o specific name but
not the other way around
- GENERIC name is always capitalized, specific name is not
- species, generic ans specific name is italicized when written
- it is always singular
Homology compares animals by...? - Answer-looking at the orgin
Analogy compares animals by...? - Answer-comparing the function
Homoplasy compares animals by...? - Answer-what they look like

one common ancestor
, A Paraphyletic group looks at...? - Answer-one ancestor and some of the
descendents
A polytomy looks at...? - Answer-a node that you don't know how the ancestors differ
Apomorphy looks at...? - Answer-changes from primitive to derived trait
Parsimony looks at...? - Answer-the common trait all the nodes share
Synapomorphy look at...? - Answer-the trait that is shared with all ancestors
Autapomorphy looks at...? - Answer-only one trait
Homoplasy looks at...? - Answer-a shared trait but evolved separately
Reversal is used when...? - Answer-there is a common trait but one or more
ancestors do not have that trait
Who was the first to observe animalcules? - Answer-Antonie Van Leeuwenhoek
A prokaryote has no nucleus or does have a nucleus? - Answer-It does not have a
nucleus
A Eukaryote has no nucleus or does have a nucleus? - Answer-It DOES have a
nuclues
