Serum albumin was detected immunologically in muscle from a mammoth that died about 40,000 years ago. Rabbits injected with ground mammoth muscle produced antibodies that react strongly with elephant albumin, weakly with sea cow albumin, and still more weakly or not at all with other mammalian albumins.

THERE have been few detailed studies of the frozen remains of woolly mammoths (Elephus primigenius)1. Here I describe a study of evolutionary change based on the grouping of the hair follicles and the distribution of hair diameters. This approach has hitherto been possible only with domestic animals2.

Compact bone from a frozen Alaskan mammoth was examined histologically and chemically to determine whether there had been any detectable alterations since the death of the animal. Histological sections closely resembled similar specimens from modern elephants. Total nitrogen and acid-extractable carbonate were at levels to be expected in fresh bone.

The article discusses a hypothesis by the curator of paleontology at the San Bernardino County Museum in Redlands, California, regarding what caused the extinction of large mammals, such as mammoths, in the late Pleistocene.

The extinction of the mammoths
The Moon and the Planets, 1980Two kinds of blanket of fine grains in the Earth's upper atmosphere are possible: a blanket of reflective dielectric particles and one of absorbing metallic particles. The first is a trigger for the onset of an ice-age, and the second a trigger for the disappearance of an ice-age. The facts support the view that it was a blanket of absorptive particles
