perkinsii), an ancestral species of protist. This unicellular organism separated from the animal evolutionary line more than a billion years ago, offering valuable insight into the mechanisms that ...

For over a century, scientists have wrestled with one of biology’s most fundamental mysteries: how the first animals evolved.

The first life forms to appear on Earth were unicellular, i.e. composed of a single cell, such as yeast or bacteria. Later, animals -- multicellular organisms -- evolved, developing from a single ...

Around 700 million years ago, the animal kingdom began to branch off from single-celled organisms. Now, scientists have uncovered molecular tools that could have assisted the leap — and ...

Researchers at the University of Tsukuba have identified a previously unknown species of unicellular organism in seawater ...

This study is published in the journal Nature. The first life forms to appear on Earth were unicellular, i.e. composed of a single cell, such as yeast or bacteria. Later, animals - multicellular ...

two deep-sea sponges and three unicellular relatives of animals: a choanoflagellate, an ichthyosporean and a filasterean amoeba. They also used existing chromosome-scale genomes of cnidarians(sea ...

The findings, published in the journal Nature, indicate that eggs existed long before the appearance of the first animals. “Though Chromosphaera perkinsii is a unicellular species, this ...
