Scientists like tidy groupings, where you are either in or you’re out.

New studies shed light on both ends of the spectrum, answering an over one hundred… Continue reading Big breakthroughs in the evolution of the brain and its connection to the stomach
Scientists find the oldest fossil of a multicellular animal and solve a 350 year old puzzle in the growth of both animals and plants alike
Meet Bicellum brasieri, a tiny, spherical animal measuring barely a thousandth of an inch discovered in the highlands of Scotland. Bicellum lived a billion years ago, yet remains a critical precursor for all animal life still to come, including ourselves. Fast forward a billion years, and scientists have also discovered the rules that govern the… Continue reading Scientists find the oldest fossil of a multicellular animal and solve a 350 year old puzzle in the growth of both animals and plants alike
