Turns out we might be very wrong about how life arose on Earth. For decades now, the prevailing scientific theory explaining the Precambrian Avalon explosion — in short, the era dating back to about ...

Why did multicellularity arise? Solving that mystery may help pinpoint life on other planets and explain the vast diversity and complexity seen on Earth today, from sea sponges to redwoods to human ...
Life and death are traditionally viewed as opposites. But the emergence of new multicellular life-forms from the cells of a dead organism introduces a “third state” that lies beyond the traditional ...
This study explains why helpful DNA changes appear often but rarely spread, because environments shift too fast for evolution ...
A team of scientists, led by the University of Sheffield in the UK and Boston College in the U.S., has found a microfossil in the Scottish Highlands which contains two distinct cell types and could be ...

Multicellular cyanobacteria flip genes between day and night
Multicellular cyanobacteria do something strikingly sophisticated with their DNA, toggling key genes on and off as day turns ...
Humanity can’t even figure out how to cryogenically freeze a single person for a short period of time. (Though NASA and Dippin’ Dots are both on the case.) But evolution has nailed keeping things ...

How do living organisms that lack a brain or nerve cells make decisions? In a new study published in May 2021 in the Proceedings of the National Academy of Sciences of the United States of America ...
New research finds that sexual reproduction and multicellularity drive diversity among different species. There are huge differences in species numbers among the major branches of the tree of life.
