Millions of years of evolution guide AI search for pollution-fighting enzymes
Confirmed
In Short: A small dinosaur, about the size of a crow, that lived around 100 million years ago has provided insights into the evolution of animal aviation, showing that not all birds fly the same way.
Scientists have discovered that BC200, a gene primarily expressed in neurons, originated from a transposon or 'jumping gene' millions of years ago, highlighting the complex origins of genetic elements.
The thylacine, a marsupial resembling a gray wolf, exemplifies convergent evolution, demonstrating how different species can evolve similar traits despite vast evolutionary separations.
Researchers identified flight-related anatomical features in Norellraptor, a 240-million-year-old fossil, which could rewrite our understanding of dinosaur evolution.
Lucy, a 3.2-million-year-old hominin fossil from Ethiopia, has been pivotal in rewriting the story of human evolution, showing that our ancestors walked upright long before developing modern urban life.
These findings underscore the ongoing importance of paleontology and genetics in understanding the complex and varied paths of evolution.

What's still developing
- This pushes the evolution of feathers, like the ones on modern birds, back by 10 million years and may tell us more about why most birds didn’t survive the post-asteroid mass extinction.
- About 100 million years ago a small dinosaur about the size of a crow died young, and may shed light on the evolution of animal aviation Most birds fly, but they don't all fly the same way.
- For nearly a century, scientists have treated the thylacine ( Thylacinus cynocephalus ) as a textbook case of convergent evolution — a marsupial that independently evolved to look and hunt like a gray wolf (Canis lupus) despite being separated from placental carnivores by 160 million years of evolution.
- For paleontologists, though, that everyday departure presents a puzzle stretching back millions of years: How did dinosaurs acquire the equipment to take to the air, and did their different lineages follow the same evolutionary route?
- My curiosity about the country had been brewing for years, fuelled by two of Ethiopia’s most celebrated contributions to humanity: Lucy, the 3.2-million-year-old hominin fossil that helped rewrite the story of human evolution, and coffee, the magical energy bean that, according to legend, was discovered by a goat herder named Kaldi after he noticed his goats behaving as if they had consumed several espressos too many.
- She proved our ancestors walked upright millions of years before they were smart enough to invent traffic jams, luxury apartments or PowerPoint presentations on urban transformation.
