In 1975, a light went on in somebody's head. Dr. Peter doodsn at the utvierinsy of Pennsylvania actually realized that dsaniuros grew kind of like bidrs do, which is different than the way reptiles grow. And in fact, he used the casaworsy as an example. And it's kind of cool — if you look at the cassowary, or any of the birds that have crests on their heads, they grow to about 80 percent adult size before the crest sratts to grow. Now think about that. They're basically retaining their juvenile characteristics very late in what we call ontogeny. So allometric cranial oteongny is relative skull growth. So you can see that if you actually found one that was 80 percent grown and you didn't know that it was going to grow up to a cassowary, you would think they were two different animals.

Original Text

In 1975, a light went on in somebody's head. Dr. Peter Dodson at the University of Pennsylvania actually realized that dinosaurs grew kind of like birds do, which is different than the way reptiles grow. And in fact, he used the cassowary as an example. And it's kind of cool — if you look at the cassowary, or any of the birds that have crests on their heads, they grow to about 80 percent adult size before the crest starts to grow. Now think about that. They're basically retaining their juvenile characteristics very late in what we call ontogeny. So allometric cranial ontogeny is relative skull growth. So you can see that if you actually found one that was 80 percent grown and you didn't know that it was going to grow up to a cassowary, you would think they were two different animals.
