The largest of these frogs could sit happily on your thumbnail. The smallest is just longer than a grain of rice.
Exceptionally well preserved 500m year old fossils show Cambrian seas were more diverse than scientists had thought.
Sometimes, two different animals will evolve to have a similar adaptation, even when they are not closely related. Flight is an excellent example.
Using the family relationships between single-celled protists alive today, researchers hypothesized what their evolutionary ancestors looked like – and then looked in the fossil record for matches.
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.
Modern animals took over our planet much more quickly than previously thought. This has both welcome and disturbing implications for the future of life on our rapidly changing planet
New Caledonian crows are famous for using tools to reach a reward. Now scientists have confirmed they can plan several steps ahead, like a chess player contemplating a series of moves.
Genetic information extracted from fossil bones of two extinct penguin species shows the geological emergence of islands plays a role in penguin evolution.
Citizen science game offered clues to why shore crabs get greener as they grow.
This is the story of how seeds came together bit-by-bit over a really long time, as plants evolved.
When geneticists create mice with special traits, there is no way to be sure that they will be inherited by the offspring. But a new genetic tool called a gene drive may fix the problem.
No area of archaeology has seen such vibrant change in recent times than how we understand our family tree. Could 2019 be the year we learn more about our mysterious ancestor Homo erectus?
As the new year gets underway, millions will make resolutions. The author explains why resolving to live in accordance with the way humans have evolved could go a long way to increasing happiness.
Did you ever consider that human beings might have a breeding season? Birth seasonality exists – and has interesting implications for childhood disease outbreaks.
Although often separated as two unique subjects in science, geology and biology have been intricately intertwined since life on Earth first evolved billions of years ago.
Why are humans the only animals with chins?
There is an urgent need to reconsider the importance of diversity. It is not a simple wealth. It is both a property of the living and an essential condition for its survival.
Ancient stone tools found in what is now Algeria show early humans likely spread across Africa more rapidly than first thought.
The marine creature amphioxus allows scientists to explore some of the steps that took place as simple creatures evolved to become complex animals.
Analysis of bones from over hundreds and thousands of years ago suggests that our skeleton today is more fragile than that of our ancestors.
