---|---|---|---|---|---|
what is gradualism it exerted a strong influence on darwins thinking | the idea that profound change can take place through the cummulitave effect of slow but continuous process (hutton and lyell
🗑
|
||||
actual father of evolution but had the inheritance of acquired traits as the mechanism otherwise known as use and disuse | lamarck
🗑
|
||||
what are the two major points of darwins orgin of species | 1. many species of organisms presently inhabiting earth are desendants of ancestral species that were diffrent form the modern species
2. the mechanism to the process is natural selection
🗑
|
||||
what is natural selection | the process in which populations can change over generations if individuals that posess certain heritable traits leave more offspring than other individuals
🗑
|
||||
what is evolutionary adaptation | an accumulation of inherited charateristics that enchance an organisms ability to survive and reproduce in a specific enviroment
🗑
|
||||
a change over time in the genetic composition of a population | evolution
🗑
|
||||
hypothesis that each strata corosponds in time to a catastrophe that destroyed many of the species living there at the time | catastrophism
🗑
|
||||
the idea that tie same geologic processes from gradualism are operating today as in the past and at the same rate | uniformitarianism
🗑
|
||||
what did darwin mean when he used the phrase decent with modification | as the descendents of an ancestral organism spilled into various habitats over millions of years they accumulated diverse modifications that fit them to specific ways of life
🗑
|
||||
two main ideas darwin developed in the orgin of species | 1. evolution explains lifes unity and diversity 2. natural selection is a cause of adaptive evolution
🗑
|
||||
process of selecting and breeding individuals with desired traits | atrifical selection
🗑
|
||||
similarity resulting from common ancestry | homology
🗑
|
||||
remnants of structures that may have served important functions in the organisms ancestors | vestigal organs
🗑
|
||||
the geographic distribution of species | biogeography
🗑
|
||||
species which is found only in a specific area | endemic
🗑
|
||||
what factors produce the variation that makes evolution possible | mutation and sexual recombination
🗑
|
||||
waht is the primary mechanism of adaptive evolution | natural selection
🗑
|
||||
what factors can alter a populations genetic composition | natural selection, genetic drift, gene flow
🗑
|
||||
what is the diffrence between microevolution and macroevolution | microevolution is change in the makeup of a population from generation to generation and macroevolution is the origination of new taxonomic groups (new abilities or features)
🗑
|
||||
why are populations important as the units of evolution | populations are the only units in which change in heritable variation from generation to generation can be observed
🗑
|
||||
what causes microevolution | small population size, migration, net mutation, non random mating, natural selection
🗑
|
||||
what causes the variation that makes evolution possible | sexual recombination and mutation
🗑
|
||||
why are mutations more rapid in microorganisms | they have a more rapid rate of reproduction
🗑
|
||||
why id sexual recombination more important than mutations in terms of evolution | sexual recombination is the way in which these mutations are spread throughout the community without it the mutation would die with the organism in which it occured
🗑
|
||||
what are the three factors that can alter a populations genetic composition | genetic drift, gene flow, and natural selection
🗑
|
||||
how does natural selection work | by accumulating and maintaining favorable genotypes in a population fitting them to their new enviroment increasing the frequency of certain genotypes
🗑
|
||||
why does natural selection have no efect on neutral variation | natural selection selects only aginst phenotyipc traits that give an organism an advantage or puts them at a disadvantage
🗑
|
||||
why cant natural selection produce perfect organisms | natural selection can only select among traits that already exist and when helpful modifications occur they are usually a compromise
🗑
