There is more to evolution than the genes species inherit.
Today, leopard tortoises are the largest species found on the Cape south coast.
Track marks are a way to fill in the blanks that sometimes exist in the body fossil record.
DNA analysis is beginning to reveal how wrong the long-accepted evolutionary tree is.
A long-term study of wild animal populations shows each generation is on average almost 20% genetically ‘better’ than their parents at surviving and reproducing.

In 1872, Charles Darwin published a book on expressions and emotions that modern science is only beginning to catch up with.

Assuming that natural selection shapes all animal and plant traits is a false impression. Natural selection is a mindless process.
Peacocking isn’t the only way to attract mates.
Darwin thought female animals were non-strategic and uniform, making similar decisions.
David Attenborough’s new BBC documentary The Green Planet shows plants are stranger than they first appear.
The annual BioArt competition highlights the hidden parts of biology revealed under a microscope.
Scientists have been using art to illuminate and share their research with the public for centuries. And art could be one way to bolster K-12 science education and scientific literacy in the public.
The diaphanous wings and striking markings of this parasitic wasp (Arotes decorus) belie its gruesome nature.
Parasitic wasps are body-snatchers — if you’re an insect. But these much-maligned creatures have saved millions of human lives by controlling the spread of the cassava mealybug.
Marianne North Gallery at Kew Gardens.
A special gallery in London’s Kew Gardens allows the visitor to travel the world via the 800-plus detailed paintings of Marianne North, Victorian-era adventurer and botanical artist.
Males elephant seals dwarf their female counterparts.
The sexual selection of larger males may be driven by an abundance – not a scarcity – of females.
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’.
A man of genius – but his ideas were not to the benefit of all humankind.

Smart people can have really bad ideas – like selectively breeding human beings to improve the species. Put into practice, Galton’s concept proved discriminatory, damaging, even deadly.
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.
In the Pacific Northwest, even though there are huge variations in environment, the Douglas fir grows everywhere.
Local adaptation allows plants and animals to thrive in a diversity of places. Sometimes adaptation sharpens patterns of where organisms live, but 85% of the time, it creates a more homogeneous world.
CRISPR isn’t a tool to fix social problems.
The role of women in futuristic drama TV series ‘The Handmaid’s Tale’ makes references to Darwin’s writings on evolution.
In the television show ‘The Handmaid’s Tale,’ Charles Darwin’s ‘Descent of Man’ makes a cameo — and its appearance makes a comment on how Gilead functions.
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.
