A Ticking Evolutionary Clock

How quickly will a gene’s rate of evolution slow to a crawl?

Larger timescales give a clearer picture of evolution.

Evolution Runs Faster on Short Timescales

Examine evolution over the course of years or centuries, and you’ll find that it progresses much more quickly than it does over geologic time.

Why Did Life Move to Land? For the View

The ancient creatures who first crawled onto land may have been lured by the informational benefit that comes from seeing through air.

How Life (and Death) Spring From Disorder

Life was long thought to obey its own set of rules. But as simple systems show signs of lifelike behavior, scientists are arguing about whether this apparent complexity is all a consequence of thermodynamics.

Droplets That ‘Come to Life’

Life might have originated in droplets that behave surprisingly like living cells.

Dividing Droplets Could Explain Life’s Origin

Researchers have discovered that simple “chemically active” droplets grow to the size of cells and spontaneously divide, suggesting they might have evolved into the first living cells.
