Evolution Flashcards
(21 cards)
Traits that are passed down to offspring- not genetic
Acquired trait
Rock layers
Strata
Structures with no function
EX: appendix, tailbone
Vestigial structures
How absolute age is determined
Radiometric dating
The process by which different species evolve similar traits
Convergent evolution
Survival of the fittest
Natural selection
Two different species evolve together
Convolution
Lowest= oldest Highest= youngest
Principle of superposition
Related function, similar origin
Homologous structures
What can be determined by the principle of superposition?
The age of fossils (relative age)
Closely related functions, not same structure
Analogous features
In order to be considered an evolutionarily favorable trait, the trait must increase the individual’s…
Ability to survive and reproduce
Four parts of darwins theory of natural selection
Overproduction, genetic variation, struggle to survive, differential reproduction
How does antibiotic resistance in bacteria illustrate natural selection?
Increases its survival rate/ reproduction rate (natural selection)
Created uniformitarism
Lyell
Thought some organisms become extinct, “catrostrophism”
Cuvier
What did Darwin infer about the finches of the Galápagos Islands having different shapes and sizes of beaks?
They are different things, same ancestors
According to Darwin, evolution occurs because of…
Natural selection
The strongest evidence for evolution comes from the…
Fossil record
Humans choosing traits/parents
Dogs
Artificial selection
An organism exhibits high fitness if…
It’s offspring live long enough to reproduce
More babies= more fit
