Many of these methods were also almost entirely exclusive (until learned) to one group, and there is often a distinct and conclusive difference between Neanderthal and Homo-sapiens tool making methods.
While it can be acknowledged that inter-species violence did indeed occur, archaeological evidence that Neanderthals were wiped out by encroaching Homo-sapiens populations remains inconclusive.
If, in the year AD 1600, you had asked an educated European how old the planet Earth was and to recount its history he would have said that it was about 6000 years old and that its ancient history was given by the biblical account in Genesis.
If you asked the same question of an educated European in AD 1900 you would have received a quite different answer.
But Bioluminescence is everywhere in nature — species of phytoplankton, disturbed by propellers, glowing in the wake of passing ships at sea is a common example, but just one of many.
Fish, squid, bacteria, worms, fireflies and a host of other animals produce their own light, and the reasons they do it—from defense to attracting a mate— are just as varied.
Read about how, in fact, the chances are much wider than most think.The study also found with the same probability that modern humans and Neanderthals overlapped in Europe for between 2,600 and 5,400 years.Most recent numbers based on improved radiocarbon dating indicate that Neanderthals disappeared around 40,000 years ago, which overturns older carbon dating which indicated that Neanderthals may have lived as recently as 24,000 years ago, Several finds in both Homo-sapiens and Neanderthal bones indicate inter-species aggression from injuries (grooves in the bones themselves) that could only have come from spear or other projectile tips crafted with prevalent tool-making methods contemporary to the time.Take a moonlit walk through the woods, and you may notice small, glowing green mushrooms brightening your path near the bases of trees and in the underbrush.There are roughly 80 species of bioluminescent fungi scattered throughout the world, and 2015 study indicated they likely glow in the dark to attract spore-spreading bugs.
