What are the 5 evidences scientists use to support the theory of evolution?
Appendix, tailbone
An example of a Vestigial Structure
Charles Darwin
What scientist is responsible for ideas that lead to the theory of evolution?
HMS Beagle
What was the name of the ship Charles Darwin travelled on?
Naturalists
What was Charles Darwin's on the ship?
1. overproduce
2. Not all offspring will survive
3. Variations within offspring.
4. Variations can be passed on.
5. Individuals with the best variations live longer.
6. Overtime, organisms with better traits will make up the population.
What are the 6 components of Natural Selection?
The color of moths changed overtime because all of the pollution changed the tree color from white to black.
How did natural selection determine which moth color pattern is more common.
Gene Pool
all the genes in a population
Homologous Structure
similar body parts on different animals.
human's arm and a bird's wings
What is an example of a Homologous Structure?
Adaptation
a variation that makes a species successful.
Variation
differences in a population
structural, physiological, behavioral
What are three types of Adaptations?
structural adaptation examples
beak, teeth, talons, tongue
physiological adaptation examples
chemical, venom, web, enzymes
behavioral adaptation examples
environment, hibernate, migrate, store nuts, dormancy
Dormancy
adaptation trees have developed to survive cold and harsh winters.
Behavioral
What type of adaptation is dormancy?
Speciation
making a new species
Geographic isolation
What is the main force involved with speciation?
Genetic Drift
rapid change in the number of genes of an isolated group.
Divergent Evolution
developed into different species
Convergent Evolution
different species develop similar traits
Gradualism
slow and steady changes of a species
Punctuated Equilibrium
rapid evolution
