By studying rapidly evolving bacteria as they diversify and compete under varying environmental conditions, researchers have shown that temporal niches are important to maintaining biodiversity in natural systems.
Parasites comprise a large proportion of the diversity of species in every ecosystem.
A new genome-wide analysis searched for evidence of long-lived balancing selection - where the evolutionary process acts not to select the single best adaptation but to maintain genetic variation in a population. The study revealed at least six regions of the genome where humans and chimpanzees share the same combination of genetic variants.
New light has been shed on a genetic variation that may have played a key role in human evolution by two studies published by an international group of researchers this week in the journal Cell.
One of the biggest sticking points in the scientific debate over the story of human evolution and eventual diaspora from Africa has been how it is told from two opposite sides of the scientific spectrum...
The novel Natural Sciences Bibliographic Web Portal aims to provide comprehensive bibliographic information on the basic and applied life, earth and health sciences.
Magellanic penguins are listed as ‘Near Vulnerable’, however scientists want to see if concerns might be tempered or fueled by understanding the genetic diversity amongst the birds’ populations in South America.
To minimize the chance of being recognized and thus attacked by the birds they are trying to parasitize, female cuckoos have evolved different guises.
Researchers have found that bird species with multiple plumage color forms within in the same population, evolve into new species faster than those with only one color form, confirming a 60 year-old evolution theory.
Battles of sexes shown to spur adaptive sex differences
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,...
