How the Bird Eye Was Pushed to an Evolutionary Extreme
...yet it worked with no apparent blood perfusion,” said Christian Damsgaard, an evolutionary physiologist at Aarhus University. “It was a complete paradox.” For centuries this has puzzled scientists, who figured...
How Ecotypes Harbor the Genetic Memory of a Species’ Past
...On the Origin of Ecotypes Over the years, evolutionary biologists have debated whether ecotypes are a first step in the evolution of new species. Are thick- and thin-shelled snails, marine...
An Early Step on the Long, Strange Road to Photosynthesis
An ancient lineage of cyanobacteria is helping biologists uncover an early evolutionary stage of the mind-boggling process that turns light into life. Every second, trillions of watts of solar energy...
What’s the Future of Gene Editing?
...function, what they’re doing inside of cells. But taking knowledge like that and trying to weave it into a story that explains evolution or even just explains biology as we...
Why the Human Genome’s Tangled Physicality May Confound AI
...genome is no blueprint or algorithm. It is something else. The Old View Given that it’s the product of around 4 billion years of evolution, perhaps it’s not surprising that...
For the First Time, a Cell Built From Scratch Grows and Divides
...4 billion years ago, a bunch of nonliving molecules got together to form the first protocells. They fed, grew, and divided. Then, over time, evolutionary processes emerged that let these...
Is Life Just Different?
...but to explore whether it can be a scientifically productive idea. To say that living things are goal-directed isn’t really a controversial statement. Biologists ranging from the evolutionary theorist Ernst...
Why Am I Left-Handed?
...Why are 90% of people right-handed? An astronomical amount of research has gone into trying to find out. Geneticists, developmental biologists, behavioral and cognitive psychologists, neuroscientists, and evolutionary biologists all...
