Molecular 'hats' allow in vivo activation of disguised signaling peptides
When someone you know is wearing an unfamiliar hat, you might not recognize them. Georgia Institute of Technology researchers are using just such a disguise to sneak biomaterials containing peptide signaling ...
Oxygen levels were only 0.1 percent of today's levels for roughly billion years before rise of animals
(Phys.org) —Geologists are letting the air out of a nagging mystery about the development of animal life on Earth.
New evidence of ancient multicellular life sets evolutionary timeline back 60 million years
(Phys.org) —A Virginia Tech geobiologist with collaborators from the Chinese Academy of Sciences have found evidence in the fossil record that complex multicellularity appeared in living things about 600 ...
Study shows wild monkeys can learn new tricks from watching training videos
The ABC's of animal speech: Not so random after all
The calls of many animals, from whales to wolves, might contain more language-like structure than previously thought, according to study that raises new questions about the evolutionary origins of human language.
Worm-like creature with legs and spikes finds its place in the evolutionary tree of life
One of the most bizarre-looking fossils ever found - a worm-like creature with legs, spikes and a head difficult to distinguish from its tail – has found its place in the evolutionary Tree of Life, definitively ...
How mantis shrimp evolved many shapes with same powerful punch
The miniweight boxing title of the animal world belongs to the mantis shrimp, a cigar-sized crustacean whose front claws can deliver an explosive 60-mile-per-hour blow akin to a bullet leaving the barrel ...
Sea creatures will get bigger and bigger (if we don't eat them first)
When life on Earth began around 3.6 billion years ago, all organisms were small. Indeed, it took some 2.5 billion years to evolve any organism that grows larger than a single cell.
Who cares? Why evolution suggests parenting responsibility is seldom equally shared
Why is caring for young shared unequally between the sexes in so many animal species? Research from the University of Bristol, UK suggests that small initial differences which predispose one sex to care more ...
Cold-blooded animals grow bigger in the warm on land, but smaller in warm water
Scientists studying arthropods, the group of cold-blooded animals that includes crabs and insects, have found that individuals within species living on land tend to grow to a larger size in the warm and nearer ...
Distant species produce love child after 60 million year breakup
A delicate woodland fern discovered in the mountains of France is the love child of two distantly-related groups of plants that haven't interbred in 60 million years, genetic analyses show.
Having a strong personality may be the difference between thriving and failing, according to new research
When the chips are down, having a strong personality may be the difference between thriving and failing, according to new research which studied how aphids reacted when faced with predatory ladybirds.
Fewer viral relics may be due to a less bloody evolutionary history
Humans have fewer remnants of viral DNA in their genes compared to other mammals, a new study has found. This decrease could be because of reduced exposure to blood-borne viruses as humans evolved to use tools rather than ...
New research shows our seas are in trouble
New research by the University of Sheffield has warned of the increasing risk of extinction to our marine life.
