Tiny algae shaped the evolution of giant clams (colorado.edu)
Giant clams, some of the largest mollusks on Earth, have long fascinated scientists. These impressive creatures can grow up to 4.5 feet in length and weigh over 700 pounds, making them icons of tropical coral reefs.

Giant, Mysterious Spires Ruled the Earth Long Before Trees Did (smithsonianmag.com)
When land plants were still the relatively new kids on the evolutionary block and the world’s tallest trees reached only a few feet in height, giant spires of life poked from the Earth.

Scientists Re-Create the Microbial Dance That Sparked Complex Life (quantamagazine.org)
Evolution was fueled by endosymbiosis, cellular alliances in which one microbe makes a permanent home inside another. For the first time, biologists made it happen in the lab.

What fossilized dino feces can tell us about their rise to dominance (arstechnica.com)
Paleontologists have long puzzled over how the dinosaurs—originally relatively small and of minor importance to the broader ecosystem—evolved to become the dominant species some 30 million years later. Fossilized feces and vomit from dinosaurs might hold important clues to how and why this evolutionary milestone came about, according to a new paper published in the journal Nature.

How human brains got so big: cells learned to handle stress that comes with size (nature.com)
Humans have evolved disproportionately large brains compared with our primate relatives — but this neurological upgrade came at a cost. Scientists exploring the trade-off have discovered unique genetic features that show how human brain cells handle the stress of keeping a big brain working. The work could inspire new lines of research to understand conditions such as Parkinson’s disease and schizophrenia.

The eukaryote, the first cell to get organized (quantamagazine.org)
Three billion years ago, life on Earth was simple. Single-celled organisms ruled, and there wasn’t much to them. They were what we now call prokaryotic cells, which include modern-day bacteria and archaea, essentially sacks of loose molecular parts. They swirled together in shallow, primordial brews or near deep-sea ocean vents, where they extracted energy from the environment and reproduced by dividing one cell into two daughter cells.

Scientists predict and witness evolution in a 30-year marine snail experiment (phys.org)
Snails on a tiny rocky islet evolved before scientists' eyes. The marine snails were reintroduced after a toxic algal bloom wiped them out from the skerry. While the researchers intentionally brought in a distinct population of the same snail species, these evolved to strikingly resemble the population lost over 30 years prior.
