Human evolution

“Junk DNA” is expressed differently in chimps and humans — and makes a difference in brain types

At GenEng and BioTech mag: "In a new study, stem cell scientists at the Lund University, Sweden, explore the role of non-coding regions of the genome—previously deemed to be functionless “junk” DNA—and find humans and chimpanzees use a part of their non-coding DNA in different ways. This they claim affects how and when the human brain develops." Read More ›

Science Uprising 8: Why materialism needs ape ancestors

Klinghoffer: It "cuts to heart of the mystery of human origins. “Human Evolution: The Monkey Bias” features geologist Casey Luskin and biologist Jonathan Wells, showing that materialism is wed to ape origins for humans because the philosophy’s whole picture of reality demands it." Read More ›

On the preprint server: Human micro proteins that sprang from nothing

Researchers: " Given their short length it is plausible that some of these functional microproteins have recently originated entirely de novo from non-coding sequence. Here we test the possibility that de novo gene birth can produce microproteins that are functional 'out-of-the-box'. " So is everybody a creationist now but some people are in denial about it?

Researchers: Our genetic history shows telltale signs of periods of starvation

From findings: Follow-up experiments in mice pointed to a potential explanation for why: the deletion appeared to limit male animals’ size when fed a calorie-restricted diet. This sort of growth limitation could help males survive lean times but limit their reproductive success in times of plenty. Read More ›

Will bionic hands ever be as good as natural hands? Researchers are certainly trying…

A recent internet-savvy bionic hand, developed by an American neuroscientist and computer engineer, is the most flexible yet, with sensory feedback. But will we ever outdo nature? Why or why not? Read More ›

Major Neanderthal cave discovery at Gibraltar

So far, no burial site has been found in the caves, and Finlayson speculated that digging down from the chamber at the apex of the cave could lead to side chambers and perhaps even a site where the Neanderthals placed their dead. Read More ›

Oldest footprints in North America —children’s — made at 22,500 years ago

Researchers are very pleased: “I think this is probably the biggest discovery about the peopling of America in a hundred years,” he says. “I don’t know what gods they prayed to, but this is a dream find.” Read More ›

Shell beads from Morocco found at 142,000 years ago

It’s fair to say that all clothing is a form of communication. True, we need clothing for warmth and protection but few people would wear tea cozies or aluminum siding, even if they theoretically work. Even back when most clothing was animal products, the type of skin or leather and any adornments thereon could probably tell us a lot. And beads? They serve no purpose except communication.

World’s oldest art raises question: Is it art?

Researchers would not be asking if it is art if it were not so old (between 169,000 and 226,000). The underlying assumption seems to be that humans did not think imaginatively in those days. The evidence seems to contradict the evolutionary assumption. Read More ›
