| exact definition of evolution |
|
Definition
| the change of genetic makeup over time |
|
|
Term
| what are the evidences of evolution |
|
Definition
| Fossils, Comparative Anatomy, Comparative Embryology, Comparative Biochemistry, Vesitgial Structures |
|
|
Term
|
Definition
| teeth, bone etc found in rock pits, ice and amber(tree fossil) |
|
|
Term
|
Definition
| minerals replace the cells of organism |
|
|
Term
|
Definition
|
|
Term
|
Definition
| hollow places in rocks from organism decay |
|
|
Term
|
Definition
| formed by minerals deposited in molds |
|
|
Term
| homologous vs anaologous structures |
|
Definition
| homologous: same structure and same origin anaologous: same structure and diff origin |
|
|
Term
| how is comparative embroyology proof of evolution |
|
Definition
| the types of gastrula, tail, teeth, larvae |
|
|
Term
| how is comparative biochemistry proof of evolution |
|
Definition
| similar metabolic processes, similar respitory processes, similar enzymes, similar genetic info |
|
|
Term
|
Definition
| appear useless now but had ancestor use |
|
|
Term
| examples of vestigial structure |
|
Definition
| appendix (useless for humans) (herbivores for cellulose digestions) -Tails (coccyx) for humans -Splints in horses (two sided toes) -python's legs |
|
|
Term
|
Definition
| to lesson intraspecies competition |
|
|
Term
|
Definition
| long term result from a geographic barrier within the same species…leading to them not being able to breed |
|
|
Term
|
Definition
| classifying based on phylogeny history |
|
|
Term
|
Definition
| evolutionary history of a group of organisms |
|
|
Term
| what did lamark believe in |
|
Definition
| -change can happen during the life of the species and that change can be inherited -the use or disuse of organs can be transmitted to offspring which makes it more useless/useful next generation |
|
|
Term
|
Definition
| no because it is proven that only DNA can be inherited |
|
|
Term
| what is the order of Darwinian evolution |
|
Definition
| 1 overpopulation 2variations (with occasional mutation) 3 competition (struggle for survivial) 4natural selection (survival of the fittest) 5inheritance of the variations (best live to reproduce 6Evolution (result of the above) |
|
|
Term
| which of the Darwinian steps has the biggest influence from environment |
|
Definition
| natural selection because that's when organisms die or live on |
|
|
Term
|
Definition
| number of same species in a given location |
|
|
Term
|
Definition
| sum of all alleles in a population |
|
|
Term
|
Definition
| % of population with a particualar (dominant or recessive) |
|
|
Term
| what are the 5 conditions that must be met inoder for no evolution to occur |
|
Definition
| large population, no mutations ever, mating is perfectly random, no migration in or out of the popualtion, equal success of reproduction |
|
|
Term
| how to find the chances of offspring based on gene pool domminant vs recessive (Hardy-Weinberg equation) |
|
Definition
| p^2 + 2pq + q^2 = 1 , p is dominant allele, q is recessive allele |
|
|
Term
| why doesn’t the hardy-weinburg equillbrium work |
|
Definition
| Natural selection (the best life on..),, Mutation , Assortive Mating, Genetic Drift(change in gene pool due to chance), Gene Flow (migration) |
|
|
Term
|
Definition
| evolution due to mating change and barriers formed (or lack of) |
|
|
Term
|
Definition
| variations, environment change, migration, lucky adaptations, natural selections and isolation |
|
|
Term
|
Definition
|
|
Term
|
Definition
| emerging number of lineages from a single ancestor |
|
|
Term
|
Definition
| a result of a adaptive radiation which is when the organism has a different lifestyle |
|
|
Term
|
Definition
| less competition thus letting the species thrive |
|
|
Term
|
Definition
| when two different evolution tree leads to the similiarties between two different organisms |
|
|
Term
|
Definition
| when evolution leads to organisms becoming very different |
|
|
Term
|
Definition
| when two different evolution trees never meet |
|
|
Term
| how does geographic isolation lead to evolution |
|
Definition
| because less gene flow is occurring so they end up changing due to different adaptations to different environments (via Natural selection) |
