Mars was warmer and wetter long ago. If anything was alive there, what came next was either a tragedy or a masterclass in survival.
After more than a million years of separation, two branches of humanity reunited around 300,000 years ago, suggests new research.
Science writer Matt Ridley joins us to discuss how “Darwin’s strangest idea” makes us all a bit feather-brained (in a good way).
We need a "theory that explains the evolution of evolution," argues theoretical physicist Sara Imari Walker.
The Universe changes remarkably over time, with some entities surviving and others simply decaying away. Is this cosmic evolution at work?
Some biologists believe natural selection produces animals that are just good enough. Dawkins disagrees.
The true story of the shot that "reverberated through England" when science collided head-on with religion.
For billions of years on Earth, life was limited to simple unicellular, non-differentiated organisms. In a mere flash, that changed forever.
"Superhabitable" planets might be real, but Earth is probably as good as it gets.
Thinking about the problem of meaning is unsettling because it introduces us to a list of solutions that all feel a bit insane.

That scary swirling void from which nothing can escape is our perfect universal translation tool.
At least one of Earth's creatures is able to survive the vacuum of space.
Darwin missed an amazing example of evolution.
Evolution repeatedly hit upon this solution simply because it works.
Bathybius haeckelii was briefly thought to be the link between inorganic matter and organic life.
Are there any advantages to looking so cumbersome?
Human beings are descendants of these early tetrapods – at least those who made a new life on land.
While becoming a monk is an evolutionary dead end for the individual, celibacy reaps benefits for the group as a whole.
New research finds that dinosaurs were already adapted to living in cold climates before the end-Triassic mass extinction. But how?
Genetic analysis reveals that a specimen collected in 2019 is the same subspecies as one caught more than a century earlier.
There’s an enormous evolutionary advantage for flamingos to stand on one leg, but genetics doesn't help. Only physics explains why.
It's not about leaves in tall trees.
All life forms, anywhere in our Universe, are chemically connected yet completely unique.
Symmetrical objects are less complex than non-symmetrical ones. Perhaps evolution acts as an algorithm with a bias toward simplicity.
Scientists across a range of disciplines have helped solve Darwin's dilemma.
Mutations that confer malaria resistance occur more frequently in people who live in regions where the disease is endemic.
From crocodiles to birds, certain animals managed to survive some of the worst extinction events in world history.
