(Phys.org)—For a long time, biologists have considered sex to be an inherent trait of multicellular life, while microbial eukaryotes were considered to be either optionally sexual or purely clonal. From this perspective, ...
In their struggle to survive and prosper, multicellular organisms rely on a complex network of communication between cells, which in humans are believed to number about 40 trillion. Now, in a study published in Nature Communications, ...
