While most hummingbirds primarily use their beaks to drink nectar from flowers, male long-billed hermit hummingbirds also use theirs as weapons during mating.
A cross-disciplinary team is calling for public discussion about a potential new way to solve longstanding global ecological problems by using an emerging technology called “gene drives.”
Writing about the weird soft-bodied fossils found in the Burgess Shale in the Canadian Rockies, paleontologist Stephen Jay Gould noted that of 25 initial body plans exhibited by the fossils, all but four were quickly eliminated.
A new study of how biodiversity arises, by evolutionary biologists at the University of Massachusetts Amherst, shows how a mutation in a single gene during development can lead to different consequences not only in how animals' skull and jaw are shaped, but how this leads to different feeding strategies to exploit different ecological niches.
Many of us might think, by looking at friends and family, that people tend to marry someone similar to them – and a new study in the journal Proceedings of the National Academy of Sciences has found that these similarities often go beyond more than skin deep.
Domestication genes tend to be insensitive to the rest of the genome and to the environment. Could finding this subset of robust genes have slowed things down?
scientists discovered three specimens, one female and two males, belonging to a new fossil stick insect referred to as Cretophasmomima melanogramma, in Inner Mongolia at the Jehol locality
A single gene regulates the complex wing patterns, colors and structures required for mimicry in swallowtail butterflies
Researchers from the University of Helsinki analyzed thoroughly the commonly occurring genetic variation in chromosome X, one of the two sex-determining chromosomes, in almost 25,000 Northern European individuals with diverse health-related information available.
Introducing a new approach that combines evolutionary and engineering analyses to identify the targets of natural selection
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,...
