The earliest creatures that can be identified as ancestors of modern humans are classified as australopithecines (literally “southern apes”). The first specimen of these hominins to be found (in 1924) was the skull of a child from a quarry site at Taung in what is now the North-West province.

But Berger’s finds at Malapa, dubbed Australopithecus sediba, proved amenable to a technique called uranium-lead dating. At two million years, they are not as old as the earliest known fossil of the genus Homo in East Africa—a 2.8 million-year-old jaw found recently at a site called Ledi-Geraru, in Ethiopia.

Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa. Early humans first migrated out of Africa into Asia probably between 2 million and 1.8 million years ago.

Neanderthal-inherited genetic material is found in all non-African populations and was initially reported to comprise 1 to 4 percent of the genome. This fraction was refined to 1.5 to 2.1 percent. Approximately 20 percent of Neanderthal DNA survives in modern humans.

Nuclear DNA (DNA) indicates close affinities with Neanderthals. Denisovans apparently interbred with modern humans, with about 3–5% of the DNA of Melanesians and Aboriginal Australians and around 7–8% in Papuans deriving from Denisovans.

“They were believed to be scavengers who made primitive tools and were incapable of language or symbolic thought.”Now, he says, researchers believe that Neanderthals “were highly intelligent, able to adapt to a wide variety of ecologicalzones, and capable of developing highly functional tools to help them do so.

What did Neanderthals look like? Neanderthals had a long, low skull (compared to the more globular skull of modern humans) with a characteristic prominent brow ridge above their eyes. Their face was also distinctive. The central part of the face protruded forward and was dominated by a very big, wide nose.

We both evolved from a common ancestor, thought to be Homo heidelbergensis. It follows that, if Neanderthals also wore clothes, clothes were invented more than once and the Neanderthals invented them before we did. The Neanderthals probably donned simple fur cloaks, according to a study published in August 2016.

Early modern humans dressed for ice age success – Neanderthals, not so much. An analysis of animal remains at prehistoric hominin sites across Europe suggests modern humans clad themselves in snug, fur-trimmed clothing, while Neanderthals probably opted for simple capes.

Instead, the threads of at least some Ice Age women included caps or snoods, belts and skirts, bandeaux (banding over the breasts) and bracelets and necklaces — all constructed of plant fibers in a great variety of cloth, from twined and basket wear to plain weaves.

It is likely, however, that wild greens, roots, tubers, seeds, nuts, and fruits were eaten. The specific plants would have varied from season to season and from region to region. And so, people of this period had to travel widely not only in pursuit of game but also to collect their fruits and vegetables.

Cavemen ate fish and lean meats. They ate the eyes, tongue, bone marrow, and organs. These days, people will not eat most of these parts of an animal, although those parts contain enough fat to satisfy a healthy diet.

Eating Meat and Marrow The diet of the earliest hominins was probably somewhat similar to the diet of modern chimpanzees: omnivorous, including large quantities of fruit, leaves, flowers, bark, insects and meat (e.g., Andrews & Martin 1991; Milton 1999; Watts 2008).

(Archaeologists call this peak the Last Glacial Maximum.) During this time, between 26,000 and 19,000 years ago, ice sheets were at their greatest extent. Evidence from Chiquihuite Cave, therefore, strongly suggests that humans were present in North America well before Clovis.

A true Hothouse Earth emerged when carbon dioxide levels reached something like 800ppm – about double those of today. This was the world of the dinosaurs, 100m years ago. There was little or no ice on Earth and the polar regions had forests and dinosaurs which were adapted to living half the year in darkness.
