At Quanta: "Now, in a paper appearing today in Science Advances, an international team of researchers led by Daniel Rokhsar, a professor of biological sciences at the University of California, Berkeley, has tracked changes in chromosomes that occurred as much as 800 million years ago. They identified 29 big blocks of genes that remained recognizable as they passed into three of the earliest subdivisions of multicellular animal life." Okay, but all this information exploding such a long time ago… ? Read More ›

Margaret Helder comments on the study: "Lots of algae exhibit clumping together in groups. This is not the definition of multicellularity. There are quite a number of colonial relatives of Chlamydomonas, for example like Eudorina, Pandorina and Volvox. They are not evolving into anything." Read More ›

From the paper: "For example, do all lineages and clades share an ancestral developmental predisposition for multicellularity emerging from genomic and biophysical motifs shared from a last common ancestor, or are the multiple origins of multicellularity truly independent evolutionary events?" Stuart Newman is one of those The Third Way scientists seeking an alternative to sterile Darwinism. Read More ›
