Doing its own thing: the eastern coyote, or coywolf, is a mix of coyote, wolf and dog which has spread across eastern North America.

A wildlife biologist argues that the canid in eastern North America – known as the eastern coyote, or the coywolf by some – deserves to be classified as a separate species.

We've bred them into all shapes and sizes, but dogs haven't been around for long enough to have evolved beyond Canis familiaris.
One of the several precious giant tortoises recently found on Volcano Wolf, Galápagos Islands.
When 100-year-old giant tortoise Lonesome George died in 2012, the world thought his species was lost forever. We went to the Galápagos Islands looking for 'extinct' tortoises – and we found them.
Fragments of woodland surrounded by cleared land in south west Australia.
Australia may have reputation for vast areas of wilderness, but in reality the continent's ecosystems have been chopped and diced. Now we need to protect what's left.
Professor Lee Berger from the University of the Witwatersrand holding the skull of Homo Naledi.
The big question being asked is: where does Homo naledi fit in the evolutionary tree? Assessing the similarity or dissimilarity between fossil skulls has provided a possible clue to the answer.
The skull of Homo naledi is built like those of early Homo species but its brain was just more than half the size of the average ancestor from 2 million years ago.
Despite claims about its age, puzzling combinations of features from Homo naledi gives it an uncanny resemblance to human beings.
Mass extinctions are more complicated than ‘strength in numbers’.
Being big – larger than a dog – increases the risk of being wiped out in a mass extinction.
What’s in a name? Plenty, if it is a dinosaur such as the Changyuraptor, a genus of the ‘four-winged’ predatory dinosaur.

A dinosaur's name says something about the dinosaur itself. They are grouped together according to similarities they share, which also indicates their ancestral relationships to one another.
This selection of stone tools provides a glimpse into the implements used by Africans 50 000 to 60 000 years ago.
Stone tools have been integral to the way archaeologists have told the human story.
A Steller sea cow skeleton: extinct in 1768.
Analysis of extinction rates over the past centuries shows that humans are causing the sixth mass extinction in the history of the Earth.
