Answer:speciation
Explanation: Speciation is the evolutionary process by which populations evolve to become distinct species. There are four geographic modes of speciation in nature, based on the extent to which speciating populations are isolated from one another these are allopatric, peripatric, parapatric, and sympatric. Speciation may also be induced artificially, through animal husbandry, agriculture, or laboratory experiments.
Am certain that the factor that prevents us from finding fossils from the Precambian era is that Most rocks from that era are deeply buried. The precambrian is the informal name for the large expanse of time preceding the current Phanerozoic Eon. It began with the Earh's Formation about 4.5 billion years ago and lasted until the advent of multicellular life about 542 million years ago.
Okay. About 71% of the Earth's surface is water. And salt water holds about 96.5% of all the Earth's water. The remaining 3% of freshwater is found in Glaciers and ice caps making it difficult to use because it is frozen. Other places freshwater can be found is: Lakes, swamps, rivers and the atmosphere. I hope this helps!
