A primordial developmental toolkit shared by all vertebrates, and described by a theory of the mathematician Alan Turing, sets the growth pattern for all types of skin structures. In 1952, well before ...

Prehistoric sexual proclivities helped to shape the human genome, according to a study 1 of genetic material from three female Neanderthal specimens. The analysis suggests that female Homo sapiens and ...

A new study helps bring the incredible color and pattern variation in butterflies into focus. The results align with a growing body of evidence that suggests butterfly-wing diversity really boils down ...

Shared features of connections between brain hemispheres likely originated in early mammalian ancestors, predating the evolution of the corpus callosum, a study suggests. The brain's left and right ...

An international team of scientists, led by geneticists from Trinity College Dublin, have sequenced the genomes from ancient goat bones from areas in the Fertile Crescent where goats were first ...

Butterfly wing patterns have a basic plan to them, which is manipulated by non-coding regulatory DNA to create the diversity of wings seen in different species, according to new research. Butterfly ...

Metallurgists have puzzled for several centuries as to how the unique patterns on the ancient Damascus blades were formed. Using a modern metallurgical computational software package, the relevant ...
