Summers says that one-way flow could explain why archosaurs "went from bit players to dinos" when Earth's oxygen levels dipped suddenly about 250 million years ago following a major extinction event.
They asked me to come in and talk about things like fish shapes and colors, and I ended up teaching an essentially graduate-level ichthyology course to the Pixar staff.
For three years, Summers was Pixar Studios' ichthyologist, introducing its artists to the mysteries of the sea.
Last year's movie smash Finding Nemo impressed many marine biologists with its scientific accuracy. Alison Abbott meets the young expert in fish biomechanics who helped to breathe life into the film's stars
Summers, who will co-teach the class with Matt McHenry, is the first UC Irvine researcher to produce a class podcast.
How does a cownose stingray, with no bones in its jaws, chomp on hard-shelled prey such as mussels and snails? In the same way a fossilized animal becomes hard as rock: with minerals, reports biologist Adam Summers
Adam Summers, an expert on biomechanics at the University of California at Irvine, says that in today's world, the heaviest living flying birds weigh no more 40 pounds.
We were floored," said Adam Summers, an evolutionary biologist at UCI. "Everyone knows that spiders spin silk from spinnerets on their hind-ends (abdomen area). But we had no idea that this charismatic spider (the zebra tarantula of Costa Rica) also could do it with their feet."
