A species of mainly marine multicellular animals – sponges, recognized as the most distant relative of a person.
This conclusion was reached by scientists at University College London, Great Britain, writes the journal Science Advances. But the researchers found that other marine creatures, ctenophores, have much more in common with humans than sponges. For example, nerve cells, muscles, and the like.
However, the scientists emphasized that cathenophores cannot be considered an older species due to the fact that this species is developing rapidly.
Scientists have carried out a computer simulation of the evolution of jellyfish and sponges, which began with a random DNA sequence that represents some common ancestor. As a result, they obtained two sets of species with different DNA sequences and collected phylogenetic trees.
As a result, two branches of evolution were obtained, where sponges were represented as the first to separate from animals. At the same time, the branch with comb jellyfish showed incorrect results, especially when it was assumed that they were relatives of other animals. As a result, scientists concluded that sponges are the most distant relative of humans.
Remember that a joint study of scientists showed signs of the existence of previously unknown extinct ancestors of Homo sapiens.
