Hello aspirant

The 2.8 million year old specimen is 400000 years older than the reseacher thought that our kinds first emerged from. The first human fossil was discovered in ethopia and this suggests that climate change spurred the Transition from tree dweller to upright walker.

Hope this helps

Hello

• Homo sapiens , the first modern humans, evolved from their early hominid predecessors between 200,000 and 300,000 years ago. They developed a capacity for language about 50,000 years ago.
• The first modern humans began moving outside of Africa starting about 70,000-100,000 years ago.
• Homo sapiens is part of a group called hominids, which were the earliest humanlike creatures. Based on archaeological and anthropological evidence, we think that hominids diverged from other primates somewhere between 2.5 and 4 million years ago in eastern and southern Africa.
• By a million years ago, some hominid species, particularly Homo erectus , began to migrate out of Africa and into Eurasia, where they began to make other advances like controlling fire
