During periods known as Snowball Earth, between 720 and 635 million years ago, early eukaryotes — complex cellular lifeforms that eventually evolved...
Previously believed to have occurred 1.2 billion years ago, this ancient impact created the Stac Fada Member, a layer of rock that holds vital clues to...
DNA methylation is a broadly observed epigenetic modification in living systems, playing diverse functions in transcriptional regulation, transposable...
Amoebidium appalachense, a protist closely related to animals, harbors the remnants of ancient giant viruses woven into its own genetic code, according...
Fossil and molecular evidence suggests that complex multicellular organisms originated and proliferated during the Neoproterozoic Era (1,000-541 million...
Around 2.4 billion years ago, the Great Oxidation Event caused fundamental changes to the chemistry of Earth’s surface environments. However, the effect...
Understanding how complex eukaryotic cells emerged from prokaryotic ancestors represents a major challenge in biology. A main point of contention in refining...
Asgard archaea (Asgardarchaeota) are considered to be the closest known relatives of eukaryotes, organisms (including animals, plants and fungi) whose...
Protocodium sinense is the first and oldest green alga species from the Ediacaran period (635-539 million years ago) to be preserved in three dimensions,...
Asgard archaea are globally distributed microorganisms related to eukaryotes — complex organisms including animals, plants, fungi, and amoeba. However,...
Chromatin is the ensemble of genomic DNA and a large number of proteins. Despite its fundamental role in biology of eukaryotic cells, scientists lack a...
Scientists from West Virginia University have found ancient cells of prokaryotes and eukaryotes within fluid inclusions in halite crystals from the Neoproterozoic...
