Evolution
The process in which the best-adapted individuals survive and reproduce, and pass on their DNA to the next generation
Natural selection
What is a scientific model
A representation of an idea, an object or even a process or a system that is used to describe and explain phenomena that cannot be experienced directly
Phylogenetic trees and cladograms seek to arrange organisms based on
common ancestry
Give an example of Homologous structures
A bat's wing and an arm of a human
What Island did Darwin visit
Galapagos
What did Darwin study on the Galapagos Islands
Finches
What caused the barks on the tree to change colors
The affects of the industrial revolution
___________ are groups that share an immediate common ancestor
Sister taxa
Do analogous structures show evidence for a common ancestor
No
Do you think Darwin could have used biochemical evidence in his research
NO
Inherited changes to a species over time is called
Adaption
Before the Industrial Revolution which moths prevailed?
The white moths
For natural selection to occur what must be true about the population and environment (think about the moths)
the population must have a genetic variation and the variation must be favorable to the environment
Organisms may be considered successful by evolutionary biologist if they are able to
Reproduce and pass their genes to the next generation
Spiderman was bitten by a spider which caused his DNA to do what
Mutate
Give an example of artificial selection
Dog Breeding
True or False: The environment caused the white moths to turn black
False
Branch points show what on phylogenetic trees
Common Ancestor
Tailbone ect
How many differences do humans and Chimps have in their Cytochrome C
1
What is the first thing that must occur for a given population that contains genetic variation to go through natural selection
A change in the environment must occur
Why are the black moths considered most fit after the barks darkened?
They were able to camouflage from predators and survive up to reproductive age to pass their genes on
____________ is similarity due to shared ancestry
Homology
List all 5 pieces of evidence of evolution
Homologous structure
Analogous structures
Biochemical
Vestigial Structures
Embryological
What is a scientific theory
scientifically acceptable general principle or body of principles offered to explain phenomena
