Male songbirds produce a subtly different tune when they are courting a female than when they are singing on their own. Now, new research offers a window into the effect this has on females, showing they have an ear for detail. The finding provides insights not only into the intricacies of songbird attraction and devotion but also into the way in which the brain develops and responds to social cues, in birds -- and humans.
One of the oldest and most complete plesiosaur fossils recovered in North America, and the oldest yet discovered from the Cretaceous Period, represents a new genus of the prehistoric aquatic predator according to University of Calgary palaeontologists who have formally described the creature after its remains were uncovered in a Syncrude Canada Ltd. mine near Fort McMurray in 1994.
New research led by UC Davis anthropologist Tim Weaver adds to the evidence that chance, rather than natural selection, best explains why the skulls of modern humans and ancient Neanderthals evolved differently. The findings may alter how anthropologists think about human evolution.
Two paleontologists studying ancient fossils they excavated in the South Australian outback argue that Earth's ecosystem has been complex for hundreds of millions of years -- at least since around 565 million years ago, which is included in a period in Earth's history called the Neoproterozoic era.
When it comes to what we eat, men and women really are different according to scientific research presented today (March 19) at the 2008 International Conference on Emerging Infectious Diseases in Atlanta, Georgia. In general, men are more likely to report eating meat and poultry items and women are more likely to report eating fruits and vegetables.
On September 27, 2004, the front part of a baby mammoth's body was found in Olchan mine in the Oimyakon Region of Yakutia. Specialists of the Museum of Mammoth of the Institute of Applied Ecology of the North, Academy of Sciences of Sakha Republic (Yakutia), have been thoroughly studying the finding and they have published the first outcomes.
University of Queensland researchers have unlocked new evidence that could help them get to the bottom of our most common phobias and their causes.
