Biodiversity is the range and variability of life on the planet. Biodiversity is commonly a degree of version at the genetic, species, and surroundings level. Terrestrial biodiversity is usually more near the equator, that's the result of the nice and cozy weather and high number one productivity. Biodiversity isn't distributed evenly on earth, and is richest in the tropics.those tropical forest ecosystems cowl much less than 10 percentage of earth's surface, and contain approximately ninety percent of the arena's species. Marine biodiversity is typically maximum alongside coasts in the Western Pacific, in which sea surface temperature is maximum, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been growing thru time, but might be possibly to gradual in the destiny.

 

speedy environmental adjustments usually reason mass extinctions.greater than 99.9 percent of all species that ever lived on the earth, amounting to over five billion species, are envisioned to be extinct. Estimates at the variety of Earth's current species variety from 10 million to 14 million,of which about 1.2 million have been documented and over 86 percent have now not but been described.extra lately, in may additionally 2016, scientists suggested that 1 trillion species are anticipated to be on the planet presently with simplest one-thousandth of 1 percent described.the entire quantity of associated DNA base pairs on earth is envisioned at five.0 x 1037 and weighs 50 billion tonnes. In evaluation, the overall mass of the biosphere has been estimated to be as lots as four TtC (trillion tons of carbon). In July 2016, scientists stated figuring out a fixed of 355 genes from the final widely wide-spread common Ancestor (LUCA) of all organisms living on the earth.The age of the Earth is set four.54 billion years.The earliest undisputed evidence of life on this planet dates as a minimum from 3.5 billion years in the past,
