| Question | Answer |
|---|---|
| Lamarck suggested that organsisms evolve | by adaptation and that acquired characteristics can be inherited. |
| George Buffon suggested that the earth might be | older than 6,000 years |
| Darwin left Great Britain on the Beagle on | December 1831 |
| Lyell suggested gradualism which is the idea that | large changes on Earth can result from the accumulation of small changes over a very long time |
| comparative anatomy is the comparison | of body structure between different species |
| Homology is the similarity in structures due to | common ancestry |
| Alleles in a gene pool occur in certain frequencies and are symbolized by | p for relative frequency for dominant allele and q for recessive allele |
| Genotype frequencies are calculated from allele frequencies and are symbolized by | p squared, 2pq or q sqaured |
| Hardy-Weinberg formula is a mathematical representation of a gene pool that adds up all of the | genotypes in a population |
| The Hardy-Weinberg formula can be used to calculated the percentage of a human population that carries the | allele for a particular inherited disease |
| Microevolution is a generation to generation change in a population's | frequencies of alleles |
| the change in a gene pool of a small population due to chance is called | genetic drift |
| an example of genetic drift that involves reduction of alleles is the | bottleneck effect |
| an example of genetic drift that involves the movement to a new colony is the | founder effect |
| A genetic exchange with another population that tends to reduce genetic differences between populations is | gene flow |
| macroevolution includes the big changes and the | formation of new species |
| the focal point of macroevolution that can be based on two contrasting patterns is | speciation |
| prezygotic barriers prevent _______ between species | mating |
| temporal isolation | timing is off |
| habitat isolation | not mobile/ geographical barriers |
| mechanical isolation | the parts dont fit |
| gametic isolation | gametes fail to unite |
| behavioral isolation | mating call not appealing |
| hybrid inviability (zygote was formed) | fails to develop |
| hybrid sterility (zygote was formed | no functional gametes |
| allopatric speciation | mountain range separating (geographical barriers) |
| sympatric speciation | no geographical barriers |
| when the species can can coexist but no longer interbreed | polyploids |
| a structure that evolves in one context gradually becoming adapted for other functions | exaption |
| retention of juvenile body features in the adult (skull bones) | paedomorphis |
| study of the diversity and relationships in organisms (both past and present) | systematics |
| identification, naming and classification of species | taxonomy (Carolus Linnaeus) |
| the goal of classification is to reflect _____, the evolutionary history of a species | phylogeny |
| compares DNA and amino acid sequences between organisms and can reveal evolutionary relationships | molecular systematics |
| distinctive branches in the history of life | cladistics |
