Terrestrial biomes lying within the Arctic or Antarctic Circles , at high altitudes or in extremely arid areas are relatively barren of plant and animal life species diversity reaches a peak in humid lowlands at equatorial latitudes. 96 698 98

The oldest material found in the Solar System is dated to ± billion years ago (Bya). 96 85 98 By ± Bya 96 86 98 the primordial Earth had formed. The bodies in the Solar System formed and evolved with the Sun. In theory, a solar nebula partitions a volume out of a molecular cloud by gravitational collapse, which begins to spin and flatten into a circumstellar disk , and then the planets grow out of that disk with the Sun. A nebula contains gas, ice grains, and dust (including primordial nuclides ). According to nebular theory , planetesimals formed by accretion , with the primordial Earth taking 65– 75 million years (Mys) to form. 96 87 98
