Latest Michal Kowalewski Stories
Research at Virginia Tech has shown that the oldest complex life forms -- living in nutrient-rich oceans more than 540 million years ago â€“ likely fed by osmosis.
By Huntley, John Warren Yanes, Yurena; Kowalewski, Michal; Castillo, Carolina; Delgado-Huertas, Antonio; Ibanez, Miguel; Alonso, Maria R; Ortiz, Jose E; de Torres, Trinidad Abstract.- The hypothesis of limiting similarity, which postulates that morphologically and/or ecologically similar species will differ enough in shape, size, or other variables to minimize competition, has been controversial among ecologiste and paleoecologists.
Virginia Tech paleontologists, using rigorous analytical methods, have identified another explosive evolutionary event that occurred about 33 million years earlier among macroscopic life forms unrelated to the Cambrian animals.
A study of fossils from the Paleozoic Era, collected across the world, reveals that ancient brachiopods were little bothered by predators. However, the rare predation traces left on brachiopod shells by unknown assailants coupled with a subtle increase in their frequency through time may be the shadows on the wall that show killers were in the room and their numbers increased with time.
