Multicellular organisms (animals, plants, humans) all have the ability to methylate the cytosine base in their DNA. This process, a type of epigenetic modification, plays an important role in ...

Scientists have discovered the fossil of what may be the earliest multicellular animal ever found. Dating back a billion years, the microscopic fossil contains two distinct cell types, potentially ...

Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before ...

Scaling up from one cell to many may have been a small step rather than a giant leap for early life on Earth. A single-celled organism closely related to animals controls its life cycle using a ...

Unicellular organisms show surprising complexity In a paper appearing in Nature Genetics, researchers discover that in more "primitive" unicellular organisms, both the adenine and the cytosine bases ...

Living things are identified and categorised on the basis of their body design in relation to their form and function. So, the classification of life forms is closely related to their evolution ...
