Indeed, archaea and bacteria appear very similar biologically (members of both groups consist of tiny cells without much internal structure) and different from eukaryotes. However, until ...
I studied bacteria and another type of microbe called archaea from hot environments for many years to learn how they might have evolved on early Earth, but I still have so many unanswered questions.
Seeps on the deep seafloor naturally emit alkanes, which are pollutants that are potentially dangerous to life and act on global warming. Fortunately, the sediments around the seeps host microbes that ...
Three billion years ago, life on Earth was simple. Single-celled organisms ruled, and there wasn’t much to them. They were what we now call prokaryotic cells, which include modern-day bacteria and ...
One of these involves fusion between cells from domains Archaea and Bacteria: one of the cells involved in the fusion becomes the eukaryote nucleus (Martin & Muller 1998; Martin 2005; Martin et al.
But there are none. Instead, there is a yawning gulf. On one side there are the tiny bacteria and archaea, collectively known as prokaryotes. On the other side there are the huge and unwieldy ...
