Peter Ward proposes that the current man-made climate change and mass extinction event may be considered to be the most recent Medean event. As these events are anthropogenic, he postulates that Medean events are not necessarily caused by microbes, but by intelligent life as well and that the final mass extinction of complex life, roughly about 500–900 million years in the future, can also ...
The mythical Gaia was the primal Greek goddess personifying the Earth, the Greek version of "Mother Nature" (from Ge = Earth, and Aia = PIE grandmother), or the Earth Mother. James Lovelock gave this name to his hypothesis after a suggestion from the novelist William Golding , who was living in the same village as Lovelock at the time ...
More than 99 percent of all species that ever lived (over five billion) [1] are estimated to be extinct. [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]
Mega El Niños could have intensified the world’s most devastating mass extinction, which ended the Permian Period 252 million years ago, a new study found. The Great Dying once wiped out 90% of ...
In a second view, before Noah's flood, a "firmament" over the earth (Genesis 1:6–8) contributed to people's advanced ages. [20] The Bible's own (brief) explanation for these ages approaches the question from a different angle, explaining instead the relative shortness of normal lives in Genesis 6:3 (CSB): "And the Lord said, 'My Spirit will ...
Similarly, in May 2022 prokaryotic and eukaryotic microorganisms were found in crystals of halite; these could be over 800 million years old but it remains uncertain if they are alive or if they could be revived. [10] [11] In a related find, a scientist was able to coax a 34,000-year-old salt-captured bacteria to reproduce. These results were ...
Over 500 million years ago, weird complex creatures emerged on Earth. Scientists now think they know why. Katie Hunt, CNN. May 7, 2024 at 12:01 PM.
Humans [3] Quaternary extinction event: 640,000, 74,000, and 13,000 years ago: Unknown; may include climate changes, massive volcanic eruptions and Humans (largely by human overhunting) [4] [5] [6] Neogene: Pliocene–Pleistocene boundary extinction: 2 Ma: Possible causes include a supernova [7] [8] or the Eltanin impact [9] [10] Middle Miocene ...
