New research shows investing in elephant conservation is smart economic policy for many African countries.
Unprecedented study of Aboriginal Australians points to one shared Out of Africa migration for modern humans21 Sep 2016
The first significant investigation into the genomics of Aboriginal Australians has uncovered several major findings about early human populations. These include evidence of a single “Out of Africa” migration event, and of a previously unidentified, “ghost-like” population spread which provided a basis for the modern Aboriginal cultural landscape.
One of the most interesting facts about mole rats – that, as with ants and termites, individuals specialise in particular tasks throughout their lives – turns out to be wrong. Instead, a new study led by the University of Cambridge shows that individuals perform different roles at different ages and that age rather than caste membership accounts for contrasts in their behaviour.
Using ancient DNA, researchers have created a unique picture of how a prehistoric migration route evolved over thousands of years – revealing that it could not have been used by the first people to enter the Americas, as traditionally thought.
A gene for red colour vision that originated in the reptile lineage around 250m years ago has resulted in the bright red bird feathers and ‘painted’ turtles we see today, and may be evidence that dinosaurs could see as many shades of red as birds - and perhaps even displayed more red than we might think.
By following honeyguides, a species of bird, people in Africa are able to locate bees’ nests to harvest honey. Research now reveals that humans use special calls to solicit the help of honeyguides and that honeyguides actively recruit appropriate human partners. This relationship is a rare example of cooperation between humans and free-living animals.
Over the last fifty years, long-term studies following individual animals over entire lifespans have allowed insight into the evolutionary influence of social behaviour – finally fulfilling the holistic approach to evolution first suggested by Darwin, argues the author of a new milestone work on mammal societies.
Heliconius butterflies have evolved bright yellow colours to deter predators, while peppered moths famously turned black to hide from birds. A new study reveals that the same gene causes both, raising fascinating questions about how evolution by natural selection occurs in these species.
Latest research suggests a new mechanism for how sexual displays of red beaks and plumage might be ‘honest signals’ of mate quality, as genes that convert yellow dietary pigments into red share cofactors with enzymes that aid detoxification – hinting that redness is a genetic sign of the ability to better metabolise harmful substances.
