Comb jellies reveal ancient origins of animal genome regulation

These Genetic On-Off Switches Likely Emerged in Earth’s Earliest Animals

Learn about the activation and deactivation of genes over long distances of DNA — an ability that emerged in comb jellies and other early animals around 700 million years to 650 million years ago.

Comb jellies reveal ancient origins of animal genome regulation

Life depends on genes being switched on and off at exactly the right time. Even the simplest living organisms do this, but usually over short distances across the DNA sequence, with the on/off switch typically right next to a gene. This basic form of genomic regulation is probably as old as life on Earth. A new study finds that the ability to control genes from far away, over many tens of thousands of DNA letters, evolved between 650 and 700 mil…

Strange microbes give clues to the ancestor of all complex life

The origin of complex eukaryotic cells, of the type found in all plants and animals, is shrouded in mystery. Now, strange microbes from wetlands in China are helping us to understand when they first emerged, and what they were like

Chinese researchers find eukaryotes originated around 2.72 bln years ago, possibly with hydrogen origins

Chinese researchers have uncovered that eukaryotes originated around 2.72 billion years ago, earlier than the Great Oxidation Event, providing valuable insights into the evolutionary history of eukaryotes.
