how-seaweed-became-multicellular

A deep dive into macroalgae genetics has uncovered the genetic underpinnings that enabled macroalgae, or ‘seaweed,’ to evolve multicellularity. Three lineages of macroalgae developed multicellularity independently and during very different time periods by acquiring genes that enable cell adhesion, extracellular matrix formation, and cell differentiation, researchers report. Surprisingly, many ofContinue Reading

bonobos-are-more-aggressive-than-previously-thought

Chimpanzees and bonobos are often thought to reflect two different sides of human nature — the conflict-ready chimpanzee versus the peaceful bonobo — but a new study shows that, within their own communities, male bonobos are more frequently aggressive than male chimpanzees. For both species, more aggressive males had moreContinue Reading
