Evolution Flashcards
evolution definition
process when different organisms develop and diversify from each other to adapt to their environments
MRSA
Methicilin Resistant Staphylococcus Aureus: resistance against staph infection treatments, genetically different
Bajau People
adapted to have bigger spleens for more oxygenated blood to hold breath for longer
Andes People
take shorter breaths because they have less hemoglobin in their blood to adapt to thinner air
Himalayan People
have broader arteries so they take faster breaths to combat thin air
James Hutton
deep time, forces beneath earth were mountains, that were then shaped by erosion
Charles Lyell
geological processes shape Earth over time, and are still happening
Jean Baptiste Lamarck’s hypothesis
- Use and disuse
- Inheritance of acquired traits
- Tendency toward perfection
Use and disuse
Organisms can alter their organs to benefit themselves in new environments
Inheritance of acquired traits
Organisms can acquire the use of an organ in their lifetime that will be passed down
Tendency toward perfection
Organisms are constantly developing features to live in environments successfully
other pieces of evidence supporting evolution
- Fossil Records
- Homo/analogous body structures
- Embryonic development
- genetics/ molecular biology
- biogeography
Homologous Structures
same basic anatomical structures showing up in different but related species
Analogous Structures
body parts serving similar use, but different structure, not related
embryonic development
embryos of distantly related species with similar features during early development
