Biologists and anthropologists can use these flash cards to learn about the development of organisms
There are 14 flash cards in this set (3 pages to print.)
1. Print out the cards.
2. Cut along the dashed lines.
3. Fold along the solid lines.
Sample flash cards in this set:
|Polyploidy||an organism or cell having more than 2 homologous (paired) sets of chromosomes|
|Postzygotic||isolating mechanism that acts after fertilization to prevent the exchange of genes between populations|
|Prezygotic||isolating mechanism that acts to prevent the fusion of gametes from different populations|
|Punctuation equilibrium||long periods of little evolutionary change (stasis) interrupted by short bursts of rapid selection|
|Reproductive isolation||a barrier to breeding that exists due to differences in mating seasons or mating organs|
|Ring species||special case of cline in which 2 ends of cline form a loop or ring|
|Sequential evolution||occurring in a sequence|
|Sixth mass extinction||mass extinction of species cause by human activity in the past 10 thousand years|
|Speciation||formation of a new species (the result of reproductive isolation)|
|Species||a group of organisms that normally interbreed in nature to produce fertile offspring and belong to the same gene pool|
|Survival of the fittest||a natural process resulting in the evolution of organisms best adapted to the environment|
|Sympatric speciation||speciation occurring where organisms living within the same area are theoretically capable of interbreeding, but cannot because of difference in behaviour eg. Flowering times etc.|
|Variation||a difference in structure, form or function from the recognized norm or standard|
|Vestigial structures||a structure that an organism has lost some or all of its function due to evolution|
