Neanderthal and Cro-Magnon 1 skulls

Neanderthal and Cro-Magnon skulls. The Neanderthal skull (left) was found at La Ferrassie, France, in 1909, and is thought to be around 70, 000 years old. The other skull is Cro-Magnon 1, found as Les Eyzies, France, in 1868, and dated to 30, 000 years ago. Neanderthals and Cro-Magnons cohabited in Europe between about 40, 000 and 30-25, 000 years ago, when the former died out. Neanderthals had occupied the region from as far back as 350, 000 years ago. Cro-Magnons were anatomically similar to modern humans, and are their ancestors. It is not known for sure what caused the extinction of the Neanderthals, but competition with the advanced Cro-Magnons is unlikely to have helped their cause

LM of human liver showing alcoholic cirrhosis

Cirrhosis. Light micrograph of a section of human liver tissue showing cirrhosis due to excessive alcohol consumption. The liver responds to the injury or death of some of its cells by producing interlacing strands of fibrous scar tissue (brownish orange) between which are nodules of regenerating cells. The liver becomes tawny and characteristically knobbly in appearance. Cirrhosis cannot be cured, but its progress can be arrested if its cause, in this case alcoholism, can be removed.
