(Phys.org)—A team of researchers affiliated with several institutions in the U.S. has found an example of a single-celled eukaryote fossil with evidence of mineralizing in Yukon territory, Canada. In ...

Horizontal gene transfer (HGT), or lateral gene transfer, refers to the movement of genetic information between organisms outside the context of sexual recombination, including transfers between ...

An international team of geneticists and molecular biologists has discovered the first-known, free-living eukaryote to have lost its mitochondria. In their study, published in Nature Communications, ...

Mitochondria are membrane-bound components within cells that are often described as the cells' powerhouses. They've long been considered as essential components for life in eukaryotes, the group ...

For billions of years after the origin of life, the only living things on Earth were tiny, primitive cells resembling today’s bacteria. But then, more than 1.5 billion years ago, something remarkable ...

The latest Virtual Issue from Genome Biology and Evolution highlights articles that provide new insight into the deep evolutionary relationships among extant organisms and the origin of eukaryotes ...

Mitochondria are membrane-bound components within cells that are often described as the cells' powerhouses. They've long been considered as essential components for life in eukaryotes, the group ...

The Archaea was recognized as a third domain of life 40 years ago. Molecular evidence soon suggested that the Eukarya represented a sister group to the Archaea or that eukaryotes descended from ...

For billions of years after the origin of life, the only living things on Earth were tiny, primitive cells resembling today’s bacteria. But then, more than 1.5 billion years ago, something remarkable ...

In biology you must have come across the two types of cells, the prokaryotic and eukaryotic cells. These two are the most fundamental forms of life on earth. Everything living from the bacteria on ...

Molecules found in 1.6-billion-year-old Australian rocks are believed to be remnants of a “lost world” of ancient organisms that comprised the earliest complex life. “We say they are a lost world, ...
