5 Mechanisms
When a female sees a trait in a male she likes, and wants to have babies that look like him
Sexual Selection
The idea we are all related to one being
Common Ancestor
These means there are several types of an organism in one population
Variation
This variable is shown on the x-axis
Independent Variable
A line that is solid and shows a population before hand.
Bell curve
This mechanism affects those that do well in there environment
Natural Selection
Why is Embryology important
We can see that in Embryo stage, many organisms look alike.
Example: Monkies that can climb the tree and get food and not die are able to reproduce
Competition
This variable is shown on the y-axis
Dependent variable
The rock remains of an organism
Fossil
These cause RANDOM CHANGES in DNA
Mutations
These structures are similar in shape but different in function
Homologous
Out of the otters kids only 1/3 of them survive past 3 months old.
Overproduction
Where the average is still popular
Stabilizing
This English scientist is know as the "Father of Evolution"
Charles Darwin
This mechanism effects small populations and it is RANDOM
Genetic Drift
These structures are similar in function but different in shape
Analogus
Free space
Free Space
Where one extreme is favored
Directional
Visual Representation of data
Graph
The movement of traits within different populations
Gene flow
These Structures are not of use to current populations
Vestigal
Something along these lines "the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution."
Where both extremes are favored
Disruptive
