Early Humans

When Did the First Human Appear on Earth?

  • PDF
Even if people were not created, but evolved, shouldn’t there be a First Human? Who was this person? And when did he/she appear?

It sounds like a natural question, right? My parents are human... and my grandparents are also human... and my grandparents’ parents are human, too... But if we go back in time like this, when does the chain of our ancestors end? If we were created, as for example the Bible says, then of course the chain ends at our creation point. But suppose for a moment that we were not created at a point in time as the Bible tells us, but evolved rather gradually, as science tells us — then what? The chain can’t go backwards forever, because we know there were no human beings, for example, 1 million years ago...

Tracking the origins of HIV

  • PDF
Human immunodeficiency virus (HIV) may have affected humans for much longer than is currently believed. Alfred Roca, an assistant professor in the College of Agricultural, Consumer and Environmental Sciences at the University of Illinois, thinks that the genomes of an isolated West African human population provide important clues about how the disease has evolved.

HIV is thought to have originated from chimpanzees in central Africa that were infected with simian immunodeficiency virus...

A study published by Université Laval researchers and their colleagues from the Canadian Forest Service reveals that the genome of conifers such as spruce, pine, and fir has remained very much the same for over 100 million years. This remarkable genomic stability explains the resemblance between today's conifers and fossils dating...

1000pa (Nov. 5, 2012) — The largest volcanic eruption on Earth in the past millions of years took place in Indonesia 74,000 years ago and researchers from the Niels Bohr Institute can now link the colossal eruption with the global climate and the effects on early humans. The results are published in the...

Genetic mutation may have allowed early humans to migrate throughout Africa

  • PDF
A genetic mutation that occurred thousands of years ago might be the answer to how early humans were able to move from central Africa and across the continent in what has been called "the great expansion," according to new research. (Credit: © Sailorr / Fotolia)
