Proposed the theory of evolution by natural selection
Adaptation
A trait or behavior that helps a species survive.
What is the theory of natural selection?
Some organisms are better suited for their environments than others, so they will have a better chance at reproducing.
Lamarck
Said organisms could change by choosing to change their bodies.
Biogeography
The distribution of life over an area
What is artificial selection?
When humans choose what traits to breed.
Thomas Malthus
Stated that some individuals survive while others did not.
Homologous Structure.
Similar structures that came from a common ancestor. Example: human hand and whale flipper.
What are the different types of evidence to support evolution?
Hutton & Lyell.
Stated the Earth was both very old & constantly changing.
Analogous Structure
The same adaptation but evolved separately. NO COMMON ANCESTOR. Example: Bird Wings & Butterfly Wings.
What will happen to the black and white moth populations?
White moths will likely die out and black moths will be able to camouflage and survive.
Gregor Mendel
Father of genetics.
Vestigial Structure.
A body part that has no use in the current organism. Example: human appendix.
What is the main idea of endosymbiotic theory?
The mitochondria/chloroplast were bacteria that became enveloped in a eukaryotic cell.
