A new genomic analysis of an ancient Taimyr wolf bone reveals that dogs and humans may have been a match far longer than previously believed.
Earlier genome-based estimates have suggested that the ancestors of modern-day dogs diverged from wolves no more than 16,000 years ago, after the last Ice Age, but new 35,000 year-old radiocarbon dating shows the Taimyr wolf represents the most recent common ancestor of modern wolves and dogs.
Males rule in most of the animal world. But when it comes to conventional gender roles, lemurs -- distant primate cousins of ours -- buck the trend. Lemur girls behave more like boys, thanks to a little testosterone.
We may think that not wanting to live around relatives is a modern trait, but our closest anthropological relatives, modern day hunter-gatherers, choose to not live among family members as much as we think. That goes for when males and females have the choice.
“Birds of a feather flock together” is a saying that exists in a number of different languages. “Gambá cheira gambá” (opossums smell other opossums) in Brazilian Portuguese is a particularly colorful example.
The reason is that like-minded people like to hang out together across many cultures. And it seems the same is true of baboons.
"It takes a village to raise a child" is folk wisdom which means that quality communities turn out quality individuals.
It may have seemed like a new idea when First Lady Hillary Clinton said it in the 1990s but ancient societies formed cooperative groups to help raise their children. Why did that happen?
University of Utah anthropologist Karen Kramer and colleagues created an economic model where mothers had one dependent offspring at a time, ended support of their young at weaning and received no help from others and then mapped it to where mothers often have multiple kids who help rear other children.
When most people think of Vikings
, they think of rape and pillaging and longships full of fierce warriors - history was clearly written by the Normans who conquered England.
New genetic testing of Iñupiat people currently living in Alaska's North Slope has determined the migration patterns and ancestral pool of the people who populated the North American Arctic over the last 5,000 years and found that all mitochondrial DNA haplogroups previously found in the ancient remains of Neo- and Paleo-Eskimos and living Inuit peoples from across the North American Arctic were found within the people living in North Slope villages.
In a music buying industry now dominated by iTunes and music streaming sites such as Spotify, Napster, Pandora and Jay-Z’s recently released Tidal, the CD and physical music store are reportedly in sharp (and potentially terminal) decline. But a curious development in music consumption has seen vinyl, the format ostensibly rendered extinct by the compact disc with its “perfect” digital sound, make an unlikely, but significant cultural and commercial comeback.
Bournemouth University’s new Institute for Studies in Landscape and Human Evolution (ISLHE) – is exploring how techniques for documenting ancient footprints can help forensic scientists understand modern-day crime scenes.
Professor Matthew Bennett, Head of the Institute for Studies in Landscape and Human Evolution, explained why the research is needed. “Footwear impressions can provide an important source of evidence from crime scenes. They can help to determine the sequence of events and – if distinctive – can even link a suspect to multiple crime scenes.
Stone tools, shaped by striking a stone "core" with a piece of bone, antler, or another stone, provide some of the most abundant evidence of human behavioral change over time. Simple Oldowan stone flakes are the earliest things considered tools, dating back 2.6 million years, and the Late Acheulean hand axe goes back 500,000 years.
While it's relatively easy to learn to make an Oldowan flake, the Acheulean hand axe is harder to master, due to its lens-shaped core tapering down to symmetrical edges.
