Planctomycetes Are Important for Theories of the Origin of Eukaryotes and Their Nuclei Why are planctomycetes important for understanding evolution of eukaryotes? There are two major types of ...
In eukaryotes, DNA is tightly wound into a complex called chromatin. Thanks to the process of chromatin remodeling, this complex can be "opened" so that specific genes are expressed. Various ...
Foraminifera, though eukaryotic, have adapted to use chemoautotrophy to enable them to survive where oxygen and sunlight are ...
Most life on Earth relies on the sun's energy for survival, but what about organisms in the deep sea that live beyond the ...

The research team looked specifically at records of ancient marine eukaryotes — organisms whose cells contain a nucleus. Early eukaryotes later evolved into the multicellular organisms credited ...
All of the usual stuff we think of as “life”—things like trees, fungi, and animals—are eukaryotes, meaning that their cells contain a nucleus and other membrane-bound organelles.
Researchers have identified ancient proteins that may help explain how the first complex cells evolved from simpler ones over 15 billion years ago I ...
Bacteria are amongst the simplest of organisms – they are made of single cells. Their cell structure is simpler than the cells of animals, plants and fungi.
