Biologists long have known that both the appearance of organisms and their inner workings are shaped by evolution, but do the same genetic mechanisms underlie changes in form and function?
In most animal species, males and females show obvious differences in body size.
From how massive humpbacks glide through the sea with ease to the efficient way fungal spores fly, applied mathematicians at Harvard have excavated the equations behind a variety of complex phenomena.
New research on lizards supports an old idea about how species can originate.

Engineers at the University of Leeds have developed a simple technology which can be used in existing chemical reactors to ensure "right first time" drug crystal formation.
While many genetic studies have examined alcoholism among adults, identifying genes that are associated with alcohol misuse during youth is equally important, given that genetic and environmental influences on alcoholism vary across development.
Biologists have genetically mapped the sex chromosomes of several species of cichlid fish from Lake Malawi, East Africa, and identified a mechanism by which new sex chromosomes may evolve.
Travelers to the neotropicsâ€”the tropical lands of the Americasâ€”might be forgiven for thinking that all of the colorful insects flittering over sunny puddles or among dense forest understory are butterflies.
Cicadas - better known for providing the soundtrack of our hot summer are remarkably interesting animals, they are the longest living insects â€“ 17 years for some species
The Grove Snail (Cepaea nemoralis) is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk. It is one of the most common species of land snail within Europe and has been introduced to North America. C. nemoralis is the type species regarding the genus Cepaea. It is used as a model organism in citizen science projects. This snail species is among the largest due to its polymorphism and bright colors. The color of the shell is very variable, reddish, yellow,...
