Mutation Killed off the Woolly Mammoth

When a warmer climate spread across the world, mammoths were in deep trouble.  Melting snow together with predation by humans made the animals extinct.  There numbers dwindled to zero in 6,000 years.  A strange thing happened during this time.  The species tried to adapt and threw up countless mutations.  Most were destructive. | ▶ optimum not stories news. | mutations mammoths killed ◀ |
Extinction of woolly mammoth
The long dark coat, so good as insulation from the cold, became like satin and light could shine through it.  They got severe irritable bowel syndrome due to their loss of smell.    It stopped them from mating due to protein changes in the creature's urine.  | ▶ | australian| mutations ◀ |    

These changes are now known from two specimens in Siberia.  One on the mainland and another on a rock island.  It was the slightly later Wrangel Island specimen that had an over representation of genetic mutations. Those who want to save threatened species must now be careful. Inbreeding could bring about the mass genetic alterations and that kills off endangered animals. | ▶ | not. | mutations ◀        | ▶ | not | ◀ |

Natural History Museum Human Evolution Gallery

 The Human Evolution gallery at Natural History explores the origins of Homo sapiens by tracing our lineage back to when it separated from that of our closest living relatives, the bonobos and chimpanzees. Around 200,000 years ago, Africa was where modern humans developed. They have smaller faces and brow ridges, a chin that is more prominent than that of other ancient humans, and a brain case that is higher and more rounded. Modern human fossils from Israel (around 100,000 years old), Africa (around 195,000 years old), and Australia (around 12,000 years old) are among the casts on display. These fossils demonstrate that typical characteristics of modern humans evolved over time rather than emerging fully formed from Africa. They also suggest that at least two waves of people leaving Africa may have occurred, one about 100,000 years ago and the other about 60,000 years ago. We are all descendants of those who left during that second migration wave outside of Africa. Source: Natural...

Study of Tooth Enamel Indicates Neanderthal Diet Was Carnivorous

 A new study on Neanderthal dietary practices has just been published in the journal PNAS by researchers from the French National Centre for Scientific Research (CNRS) and several German scientific institutions. They were able to determine that a Neanderthal who lived in a cave on the Iberian Peninsula during the Middle Paleolithic period (50,000 years ago) ate exclusively carnivorous food using a newly developed method for studying the chemical signatures of ancient tooth enamel. This isn't the first study to find this, either. Despite this, it is a one-of-a-kind and significant discovery because it was made through the development of a novel analytical method that could be used to learn more about the diet and way of life of Neanderthals who lived in other parts of Eurasia in the distant past.   To investigate the diet and eating habits of Neanderthals, numerous research projects have been initiated. However, they have resulted in contradictory outcomes. The CNRS researchers...
