The early stages of the process through which birds evolved from dinosaurs was slow and gradual, and there was no single “missing link” separating the two different types of creatures, according to research published in Thursday’s edition of the journal Current Biology.
The grand mystery over how massive, carnivorous dinosaurs gave rise to flying birds has a simple solution, as it turns out – the meat-eaters simply kept shrinking and shrinking over a period of 50 million years.
The key characteristics of birds which allow them to fly – their wings and their small size – arose much earlier than previously thought.
Scientists are certain that sometime around 150 million years ago birds originated from a group of small, meat-eating theropod dinosaurs called maniraptorans. According to recent studies conducted around the world, the maniraptorans were very bird-like, with feathers, hollow bones, small body sizes and high metabolic rates.
John Harold Ostrom (February 18, 1928 – July 16, 2005) was an American Paleontologist who was greatly influential in the revival of scientific research on Dinosaurs. He is best known for demonstrating that Dinosaurs were less like contemporary reptiles but more closely related to large, flightless birds like the ostrich – a theory that holds its ground in the paleontological community to this day. John Ostrom was born and raised in Schenectady, New York. His father was a physician, and...
