How an organelle evolves in symbiosis with a cell: Intermediate stage sheds light on the assimilation process
Organelles in cells were originally often independent cells, which were incorporated by host cells and lost their independence in the course of evolution. A team of biologists headed by Professor Dr. Eva Nowack at Heinrich ...

Chimpanzee genes have changed over time to suit local conditions: New study
Chimpanzees are humans' closest living relatives, sharing more than 98% of our DNA. They are endangered, with fewer than 250,000 left and an annual decline of between 1.5% and 6%. This is due to habitat destruction, hunting ...

The tendency of some flowers to be 'honest' and reward pollinators with nectar is partly genetic, study suggests
Flowers can produce showy displays that appeal to pollinating insects or animals, but some "cheat" by enticing pollinators but not rewarding them with nectar. Research in New Phytologist indicates that the tendency of flowers ...

Scientists uncover principles underlying the toxicity of 'selfish' genes
Lurking within the genomes of nearly all species—including plants, fungi, and even humans—are genes that are passed from generation to generation with no clear benefit to the organism. Called "selfish" genes, they can ...

How big brains and flexible skulls led to the evolution of modern birds
Modern birds are the living relatives of dinosaurs. Take a look at the features of flightless birds like chickens and ostriches that walk upright on two hind legs, or predators like eagles and hawks with their sharp talons ...

Gorillas match chimpanzees in self-awareness study
Gorillas may have greater self-awareness than scientists previously thought. A new study finds that gorillas perform just as well as chimpanzees in tests that require awareness of their own bodies. A research team, led by ...

Genomic study indicates our capacity for language emerged 135,000 years ago
It is a deep question, from deep in our history: when did human language as we know it emerge? A new survey of genomic evidence suggests our unique language capacity was present at least 135,000 years ago. Subsequently, language ...

Snakes' secret language of ultraviolet color: A hidden world of predator evasion and camouflage
In the study of why and how animals look the way they do, color is king—at least, the range of color humans can see. A University of Michigan study has examined a color range that humans can't see and often ignore: color ...

We modeled how early human ancestors ran—and found they were surprisingly slow
Imagine the scene, around 3 million years ago in what is now east Africa. By the side of a river, an injured antelope keels over and draws its last breath. The carcass is soon set on by hyenas, who tussle with a crocodile. ...
