APB C24 Speciation
Question | Answer |
---|---|
The formation of new and distinct species in the course of evolution | Speciation |
Evolutionary change within a species or small group of organisms, especially over a short period | Microevolution |
Major evolutionary change. The term applies mainly to the evolution of whole taxonomic groups over long periods of time | Macroevolution |
A group of living organisms consisting of similar individuals capable of interbreeding and producing viable offspring | Species |
Speciation that occurs when biological populations of the same species become isolated from each other to an extent that prevents or interferes with genetic interchange | Allopatric speciation |
The process through which new species evolve from a single ancestral species while inhabiting the same geographic region | Sympatric speciation |
The situation where different species may live in the same area, but properties of individuals prevent them from interbreeding | Reproductive isolation |
When the number of chromosomes in an organism's cell doubles | Polyploidy |
A hypothesis holding that the evolution of species proceeds in a characteristic pattern of relative stability for long periods of time interspersed with much shorter periods during which many species become extinct and new species emerge | Punctuated equilibrium |
