Species evenness is a measure of the relative abundance of the different species making up the richness of an area. star. This is usually taken to be evidence for plate tectonic movement of the contents. Endemism is the ecological state of a species being unique to a defined geographic location, such as an island, nation, country or other defined zone, or habitat type; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere.

Evolution is a continuous process, and geographic variations are inevitable. Scientists have found a lot of evidence that is consistent with allopatric speciation being a common way that new species form: Geographic patterns: If allopatric speciation happens, we’d predict that populations of the same species in different geographic locations would be genetically different. The two species are active during different parts of the day. Though the modern lions have been classified into 24 sub-species on the basis of morphological differences (size, thickness of the coat, color of the coat, mane size, etc.) Gene flow, the movement of alleles across the range of the species, is relatively free because individuals can move and then mate with individuals in their new location. Which of the following is not a prezygotic isolating mechanism for two species found in the same geographical location? This is another row cap question, and it's asking water species called the only current one geographic regions. See Answer.
