A team of scientists has found the first proof that weakening and strengthening Asian monsoon rains played a key role in the evolution of mammals.

Mammals are more like their fathers genetically

You may resemble or act more like your mother, but first-of-its-kind research reveals that mammals are genetically more like their fathers.

Fossils of two 160-mn-year-old mammals found

Researchers from the University of Chicago and China's Beijing Museum of Natural History have discovered fossils of two mammals that lived more than 160 million years ago and which exhibited characteristics that demonstrate their ability to adapt to their ecological habitats since the early stages of their evolution.

New insights into mammalian evolution

Despite having a common ancestor, different mammalian species have acquired their unique characteristics by repurposing functional elements through gene regulation, says a study.

Dinosaur-killer asteroid nearly wiped out mammals too
Dinosaur-killer asteroid nearly wiped out mammals too

Many mammals came perilously close to extinction when a massive asteroid hit the earth 66 million years ago, says a study, adding that if a few lucky species did not make it through then mammals may have gone the way of the dinosaurs.

Tooth loss in birds occurred 116 million years ago
Tooth loss in birds occurred 116 million years ago

Using the degraded remnants of tooth genes in birds to determine when birds lost their teeth, researchers have found that teeth were lost in the common ancestor of all living birds more than 116 million years ago.

Wildlife numbers have plunged by more than half in just 40 years as Earth`s human population has nearly doubled, a survey of over 3,000 vertebrate species revealed on Tuesday.

Dying cells send signal to stimulate new cells in birds
Dying cells send signal to stimulate new cells in birds

Scientists have discovered new neuron growth each spring in songbirds that starts with a signal from the expiring cells from the previous fall that primes the brain to start producing stem cells.

Decoded how rib cells heal themselves

We know that mammals cannot regenerate lost limbs but they can repair large sections of their ribs. A team of US researchers has now discovered the healing power of the rib cells in both humans and mice.

Mammals originated at least 208 mn years ago

Paleontologists have affirmed the idea that mammals, an extremely diverse group that includes egg-laying monotremes, originated at least 208 million years ago, much earlier than some previous works of research suggest.

Crows, mammals grieve over loved ones` death just as humans do

A new book has claimed that crows and other animals grieve over death of their loved ones just as humans do.

Elephant`s sense of smell stronger than dogs, humans

Researchers have found that African elephants have the largest number of olfactory receptor (OR) genes ever characterised - more than twice than that of dogs and five times more than humans.

Fossil of world`s smallest hedgehog unearthed in Canada

You`ve heard of Sonic the Hedgehog, the video game character. But how about the half-pint hedgehog, the tiniest one that ever lived?

Law of urination: It takes 20 seconds to pee!

All animals - from elephants to cats - that weigh more than 3 kilogrammes take about 20 seconds to pee, scientists have found.

A ready reckoner on mammals in India

Did you know that rhinos are one of the most dangerous animals to come across on foot as they can clock 55 km an hour when they chase?

New animal species discovered in Papua New Guinea

Australian scientists have uncovered several new species of mammals in the remote forests of Papua New Guinea.
