FORMATION OF NEW SPECIES def of species process of speciation patter of change classification of nature how does it go from small variations within a species to creating a whole new species? this is the transition from microevolution to macroevolution micro= change within species, like allele frequency macro= large scale change that results in entirely new species is it possible that incremental micro change sums up to one macro change? the definition and concept of species is actually complicated. biological species concept: groups of inter-breeding populations that are reproductively isolated from other groups (they can reproduce with each other but not with other groups of animals) geography can separate species, the physical build of the animal (like lady bugs and pigs) also different courtship habits/culture. one nocturnal animal with non-nocturnal, etc however, not always possible to prove biological species through reproduction (such as if animals live far apart, how do you know they couldn’t reproduce if they were put together)
