Earth's first animals barely evolved until sex changed everything

A study from the University of Cambridge suggests that the lack of sexual reproduction in early Ediacaran animals limited evolutionary diversity for millions of years. These ancient organisms, which lacked complex organs, eventually disappeared before the Cambrian explosion.
Why it matters
Understanding the evolutionary history of early life provides critical insights into the biological mechanisms that drive biodiversity on Earth.
A new study suggests that the earliest animals on Earth may have unintentionally slowed the rise of biodiversity. According to researchers from the University of Cambridge, the way these ancient organisms reproduced limited competition and kept evolution moving at a remarkably slow pace for millions of years.
