The huge number of active coronavirus infections offers plenty of opportunity for mutations to occur and new variants to arise.

When the coronavirus copies itself, there is a chance its RNA will mutate. But new variants must jump from one host to another, and the more infections there are, the better chance this will happen.

We’re the only species that can throw at speeds that kill.
First published 150 years ago, this work is shaped by Victorian-era sexual and racial stereotypes. But at a time when other evolutionists stressed humanity’s uniqueness, Darwin emphasised our ‘lowly nature’.
Finches have evolved to feed off blood from red-footed and Nazca boobies – and we’ve seen it first-hand.
Governments will need to determine how best to allocate COVID-19 vaccinations.
When allocating resources, we prioritize members of the social groups we belong to, rather than including others in our allocations. This will determine how the COVID-19 vaccine is distributed.

As editor of the magazine for 24 years, Du Bois featured articles about biology, evolution, archaeology in Africa and more to refute the rampant scientific racism of the early 20th century.
We propose same-sex attraction evolved to allow greater social integration and stronger same-sex social bonds.
Scientists don’t ask how some people evolved to be tall. In the same way, asking how homosexuality evolved is the wrong question. We need to ask how human sexuality evolved in all its forms.
For millennia, theologians taught that the sole purpose of sex was reproductive. Now, almost everyone agrees that sex has many purposes – and benefits.
The purpose of sex may seem obvious, but it has perplexed and intrigued a variety of great minds for millennia.
An Indonesian island was home to
H. Floresiensis – but how did the dwarfed human species evolve?
New research models how the Homo floresiensis species could have evolved its small size remarkably quickly while living on an isolated island.
Darwin wondered: what if species change over time in response to their environment?
In science, we look at the evidence and try to find the theory that best explains it. And that’s what happened when it came to figuring out evolution.
Evolution has no final endpoint in mind.
If you go by editorial cartoons and T-shirts, you might have the impression that evolution proceeds as an orderly march toward a preordained finish line. But that’s not right at all.

How and why animals develop as male or female is far more complex than we ever imagined.
Modern science clashes with the idea that the rise of Homo Sapiens was a fluke.
One reason for the likes of the anti-vaxxers movement is a misplaced faith in Mother Nature.
Ever heard of lexical selection? Every time you open your mouth you change the way future generations will talk.
Male collared flycatcher, singing for multiple females.
Biologists investigated whether birds that search for multiple mates would evolve ever more elaborate songs to attract them. What they found might have surprised Darwin.
A young shore crab displaying varied colouring.
Citizen science game offered clues to why shore crabs get greener as they grow.
Why are humans the only animals with chins?
Yes, we’re still evolving.
Natural selection isn’t the only factor deciding human evolution.
Down House: the home (and garden) of Charles Darwin.
Was Darwin inspired by the tropical wildlife of his travels to discover natural selection? Actually, pigeons, worms and barnacles were far more prominent in his thinking.
