Chapter 13 Flashcards
Darwins voyage
Animals adapt to where they are living, like the food with the finch birds in their beaks
Evidence of evolution
Fossils, biogeography, comparative anatomy, comparative embryology, and molecular biology
Fossils
Shows that Dinosaurs may have turned into birds, fossilize stoned showed a dinosaur with feathers so evolution by their Skelton
Biogeography
Take one species from one place and move it somewhere else so they have to adapt.
Adapting
Comparative Anatomy
Compare animals things you see Externally. A common ancestor, compare bones to see if anything has changed, look how they evolved.
Comparative embryology
Looks alike but then changes into throat ears in mature state. As an embryo
Molecular biology
Similar genotype, may express phenotype different, but have a similar Gino code like humans and chimpanzees
Gregor
Begin modern genetics
Population
A group of individuals of the same species living in the same place at the same time. The smallest biological unit that can evolve
Population genetics
Follows genetic make up of a population over time
Sexual recombination
Random gene combinations during MEIOSIS. Mother and father’s DNA mix you never know what it’s going to be.
Gene pool
Where the next generation gets its genes
Genetic drift
Change in the gene pool of a small population due to chance bottlenecking. Reduces a population size, this produces genetic variation due to natural disaster or isolation colonization of a group.
Bottleneck in in genetic gene flow
Keep it bottled up in that community if they just marry in their population they don’t release the genetic flow.
