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 disruption: 14.5 Ma Climate change due to change of ocean ...
However, when 2,000 years ago, during the Three Kingdoms period, the Chinese inventor Ma Jun created a chariot with a built-in compass for Emperor Ming-di, it was a real wonder.
As long as species have been evolving, species have been going extinct. It is estimated that over 99.9% of all species that ever lived are extinct.

In the rainforest of northern South America, an entomologist by the name of Alfred E. Emerson spent five years on the hunt for new species. Emerson conducted three species surveys from 1919 to ...
This is a list of North American animals extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present (about 9700 BCE) [A] and continues to the present day. [1] Recently extinct animals in the West Indies and Hawaii are in their own respective lists.
A growing number of scientists believe a sixth mass extinction event of a magnitude equal to the prior five has been unfolding for the past 10,000 years as humans have made their mark around the ...
