Speciation caused by geographic division is known as allopatric speciation. This process occurs when a population is separated by physical barriers, such as mountains or rivers, leading to reproductive isolation. Over time, the isolated groups may evolve distinct traits and become separate species due to differing environmental pressures and genetic drift.

A chemical mitogenesis refers to the cell division triggering mitosis that is caused by the chemicals.
Cracks on the tongue can be caused by various factors such as dehydration, irritation from hot or spicy foods, fungal infections like oral thrush, or a condition called geographic tongue. It's best to consult a healthcare professional for a proper diagnosis and treatment if needed.
Speciation caused by the breakup of continents can occur when populations become isolated from one another, leading to genetic divergence over time. Geographic barriers like oceans, mountain ranges, or deserts can prevent interbreeding between populations, ultimately leading to the formation of new species through the process of allopatric speciation.

The greatest increase in diversity of life during evolution was likely due to the process of speciation, where one species diversifies into multiple new species over time. This can be driven by various factors such as geographic isolation, genetic mutations, and natural selection acting on different populations.

It can be by geological means (i.e. earthquakes, floods, mountains and other other geographic barriers) or population dispersal. It can also be caused by human activity that splits a population, causing geographic isolation.
Geographical isolation involves the separation of a group of organisms from the rest of the population, or a population from other populations by geographical means, be it by volcanic activity, a flood, a new river that cannot be crossed. The idea being that the population can only breed with itself and not with other populations, leading to genetic isolation. This is called the founder effect. The separated organisms can only mate amongst themselves, reducing their genetic diversity as they have a limited range of alleles. This can lead to speciation etc...

The striking gap between Saturn's A and B rings is called the Cassini Division. This division is approximately 4,800 kilometers wide and is caused by the gravitational influence of Saturn's moon Mimas, which clears out particles in that region. The Cassini Division is one of the most prominent features of Saturn's ring system, making it easily observable from Earth.
