PRESENTATION OUTLINE
The posion dart frog can be found in South America, and they are most commonly known to be lethally toxic. Anything that tries to touch and or eat the frog, will suffer a toxic meal. It can range from a mild nuerotoxin to lethal toxins.

The eye owl moth can be found in Centeral and South America. It mimics the eyes of an owl in hopes to scare off it's predators, such as smaller birds or mice.

The panther chameleon can be found in parts of Madagascar. It uses special cells in it's skin to change the color of its body based on mood as well as to blend in to the foliage. (Many believe they change their color based on their surroundings, however this in only true to the green and brown. Chameleons will not turn red on a red blanket)

Stabilizing selection is a type of natural selection in which the population mean stabilizes on a particular non-extreme trait value. Instead of white or black butterflies, you may have a more grey population.

Disruptive selection splits a population into 2 extremes. Such being only black butterflies or only white butterflies of the same species

Directional selection is where one extreme trait is favored over the other traits. Such being a mainly black butterfly species.

Sexual selection is where a male member of a species has a trait that females want, and the female of said population will choose the male with the best feature. Such being peacocks and their tail feathers.
Artifical selection is where humans use animal breeding and plant breeding to selectively develop particular phenotypic traits. Such being cows to produce the most milk

Coevolution is the influence of closely associated species on each other in their evolution. Such being a type of bird and a flower it uses for food.
Genetic drift the influence of closely associated species on each other in their evolution. Such being a population gets seperated on 2 sides of a canyon and a recessive variant becomes more promient on one side.
