[2] [3] Estimates on the number of Earth's current species range from 10 million to 14 million, [4] with about 1.2 million or 14% documented, the rest not yet described. [5] However, a 2016 report estimates an additional 1 trillion microbial species, with only 0.001% described.
Basin Groups Era begins on Earth. c. 4,450 Ma – 100 million years after the Moon formed, the first lunar crust, formed of lunar anorthosite, differentiates from lower magmas. The earliest Earth crust probably forms similarly out of similar material. On Earth the pluvial period starts, in which the Earth's crust cools enough to let oceans form.
While life on Earth is regarded to have spawned relatively early in the planet's history, the evolution from multicellular to intelligent organisms took around 800 million years. [58] Civilizations on Earth have existed for about 12,000 years, and radio communication reaching space has existed for little more than 100 years.
The authors therefore think the moon formed around 4.51 billion years ago — more than 100 million years earlier than the commonly accepted estimate. ... the study’s lead author and a professor ...
Earth formed in this manner about 4.54 billion years ago (with an uncertainty of 1%) [25] [26] [4] and was largely completed within 10–20 million years. [27] In June 2023, scientists reported evidence that the planet Earth may have formed in just three million years, much faster than the 10−100 million years thought earlier.
“For over 100 million years when dinosaurs were the dominant predators, mammals were generally small, nocturnal, and short-lived.” The pressure to stay alive eliminated the genes needed for ...
The Future Is Wild (also referred to by the acronym FIW) [1] is a 2002 speculative evolution docufiction miniseries and an accompanying multimedia entertainment franchise. The Future Is Wild explores the ecosystems and wildlife of three future time periods: 5, 100, and 200 million years in the future, in the format of a nature documentary.
