Math explains history: Simulation accurately captures the evolution of ancient complex societies
The question of how human societies evolve from small groups to the huge, anonymous and complex societies of today has been answered mathematically, accurately matching the historical record on the emergence ...
When genes play games: Algorithm helps explain sex in evolution
What do you get when you mix theorists in computer science with evolutionary biologists? You get an algorithm to explain sex.
Human Y chromosome much older than previously thought
(Phys.org) —University of Arizona geneticists have discovered the oldest known genetic branch of the human Y chromosome – the hereditary factor determining male sex.
Lizards are larger and retain heat longer in high-altitude habitats
University of Granada scientists confirm that ectotherms–like reptiles and amphibians–do follow "Bergmann's rule". The 19th-century naturalist posited thatanimals inhabiting colder climates have a larger ...
Sunlight stimulates release of climate-warming gas from melting Arctic permafrost, study says
Ancient carbon trapped in Arctic permafrost is extremely sensitive to sunlight and, if exposed to the surface when long-frozen soils melt and collapse, can release climate-warming carbon dioxide gas into ...
Long-held assumption about emergence of new species questioned
Darwin referred to the origin of species as "that mystery of mysteries," and even today, more than 150 years later, evolutionary biologists cannot fully explain how new animals and plants arise.
Coelacanth genome surfaces: Unexpected insights from a fish with a 300-million-year-old fossil record
An international team of researchers has decoded the genome of a creature whose evolutionary history is both enigmatic and illuminating: the African coelacanth. A sea-cave dwelling, five-foot long fish with ...
New proto-mammal fossil sheds light on evolution of earliest mammals (w/ Video)
A newly discovered fossil reveals the evolutionary adaptations of a 165-million-year-old proto-mammal, providing evidence that traits such as hair and fur originated well before the rise of the first true ...
Secrets to 'extreme adaptation' found in Burmese python genome
The Burmese python's ability to ramp up its metabolism and enlarge its organs to swallow and digest prey whole can be traced to unusually rapid evolution and specialized adaptations of its genes and the way ...
Ancient fossils confirmed among our strangest cousins
More than 100 years since they were first discovered, some of the world's most bizarre fossils have been identified as distant relatives of humans, thanks to the work of University of Adelaide researchers.
Picking up on the smell of evolution
UA researchers have discovered some of the changes in genes, physiology and behavior that enable a species to drastically change its lifestyle in the course of evolution.
Enlisting evolutionary biology against modern threats
To many, the term evolutionary biology encompasses the realm of fossils, dinosaurs and changes over eons.
Status shift for whale pelvic bones
For decades, scientists assumed that the relatively small pelvic bones found in whales were simple remnants of their land-dwelling past, "useless vestiges" that served no real purpose, akin to the human appendix ...
Rabbit-proof hoof: Ungulates suppressed lagomorph evolution
Closely related groups can differ dramatically in their diversity, but why this happens is a fundamental question in evolutionary biology, dating back to Darwin's observation that a few hyper-diverse groups ...
