Evolution

Each year lightning kills hundreds of millions of trees worldwide, leaving behind scorched trunks and shattered branches, but one species of tropical tree in Panama has turned this destructive force of nature to their advantage.

You don't often find crowds flocking to take in the pungent scent of rotting flesh, yet that's just what happens when a corpse flower blooms at a public garden. But this iconic endangered plant is now facing a new threat – our aversion to paperwork.

Astrophysicists have done a bit of crime scene investigation. They’ve traced radioactive elements on the seafloor back to the cosmic explosions they might have come from – and potentially linked the event to evolutionary changes in viruses in Africa.

A preserved tree fossil gives an unprecedented view into a moment 42,000 years ago when the Earth’s magnetic field went haywire, triggering environmental chaos, influencing everything from an increase in cave paintings to the Neanderthal extinction.

New research is offering some of the clearest insights into the physiological effect of loneliness ever gathered. The findings reveal a lack of social contact can shrink parts of your brain and flood your body with inflammatory proteins.

We often see the results of evolution, but not the process directly. Now, scientists have witnessed evolution unfolding in real time, as two similar lizard species encounter each other for the first time and quickly adapt to fill different roles.

A new discovery in Kenya shows that ancient human relatives crossed paths – literally. Paleontologists have discovered the first known example of fossil footprints left by two different species of ancient hominins on the same day.

Many of us have had a tooth pulled in the dentist's chair, and even with anesthetic, it's not pleasant. So spare a thought for the people who, for millennia, chose to have good teeth yanked out with no painkillers – all in the name of beauty (mainly).

Ever been caught in the crossfire of a wet dog firing droplets of water away from their fur with a mad shake? Well, they can't help it. Scientists have identified the innate sense-motor function mechanism that drives dogs to twist and spout.

Despite observations of "wasps getting drunk" and "beetles consuming beer," it has been thought that alcohol in the non-human animal world hasn't been deliberate. Ecologists challenge this theory, saying it's far more commonplace and strategic.

Most of us do it, in one form or another, but how and when humans began to kiss is still hotly debated among researchers. Now, a new evolutionary theory has been put forward, which says the origins of the kiss may date back millions of years.

A surprise discovery in the Australian outback has delivered exciting insight into the origins of complex animal life. The animal fossil, dating back half a billion years, shows when bilateral symmetry emerged – a hallmark of most life on Earth now.
