New genes linked with bigger brains identified

A number of new links between families of genes and brain size have been identified by UK scientists, opening up a whole new avenue of research to better understand brain development and diseases like dementia.

The evolution of development

On the basis of an analysis of 520 million-year-old fossils, LMU researchers show that embryonic and larval development in the early ancestors of spiders and scorpions was strikingly and unexpectedly similar to that of modern ...

Uncovering evolutionary secrets

How did the elephant get its trunk? Or the turtle its shell? How, in general, did the seemingly infinite diversity of complex animal forms on our planet arise? The scientific pursuit of how such "evolutionary novelties" come ...

Embryonic stem cells produced in living adult organisms

A team from the Spanish National Cancer Research Centre (CNIO) has become the first to make adult cells from a living organism retreat in their evolutionary development to recover the characteristics of embryonic stem cells.

Genomic analysis solves the turtle mystery

The turtle has always been considered somewhat odd in evolutionary terms. In addition to lacking the hole in the skull—the temporal fenestra—that is characteristic of the egg-laying amniotes, the structure of its shell ...
