Genetics
A new study published in the journal Communications Biology has shed light on the earliest stages in the evolution of male-female differentiation and sex chromosomes--and found the genetic origins o…
New research by University of Alberta cellular biologists is putting into question existing theories about what's responsible for organizing a central part of our cells, known as the Golgi appara…
Evolutionary biologists have now discovered that the Pygmy Marmoset – the world’s smallest monkey – is not one species but two. Pygmy Marmoset [Credit: University of Salford] Weighing just 100 grams …
For over a century, speciation -- where one species splits into two -- has been a central focus of evolutionary research. But a new study almost 20 years in the making suggests "speciation rever…
New genetic research reveals the complex demographic history of Vanuatu, explaining how Austronesian languages were retained throughout its history despite near-total replacement of early Austronesia…
An international team of researchers has produced one of the most comprehensive evolutionary pictures to date by looking at one of the world's most iconic animal families - namely elephants, and …
The tropical rainforests of Central and South America are home to the largest diversity of plants on this planet. Nowhere else are there quite so many different plant species in one place. However, t…
In an ancient DNA study published this week in the journal Nature , scientists and archaeologists from over 80 different institutions lift the veil on the genomic history of Southeastern Europe, a re…
Lizards have special superpowers. While birds can regrow feathers and mammals can regrow skin, lizards can regenerate entire structures such as their tails. Despite these differences, all have evolve…
In the Late Neolithic, a new style of pottery appears among the grave goods buried with the dead in many parts of Europe. A new genetic study shows that, with one exception, its dissemination was not…
There are no such things as "wild" horses anymore. Research published in Science overturns a long-held assumption that Przewalski's horses, native to the Eurasian steppes, are the last…
ETH scientists have been able to prove that a protein structure widespread in nature – the amyloid – is theoretically capable of multiplying itself. This makes it a potential predecessor to molecules…
It’s so impressive: a living cell is able to neatly package a big jumble of DNA, over two meters in length, into tidy, tiny chromosomes while preparing for cell division. For over a century, it has b…
