The more we learn
about how animals have evolved over millions of years, the more we learn about
ourselves. The latest example comes from Germany where scientists have studied
prosauropods. They’re dinosaurs that were quite different than other dinosaurs
of the time. Looking at fossils, they found that different prosauropods may
have been warm-blooded. Most dinosaurs were cold-blooded and their growth was
determined by their environmental conditions. Like today’s alligators and
turtles, these dinosaurs literally adjusted their growth to the environment
they lived in, and the change of seasons. The warm-blooded prosauropods
actually grew to certain heights independent of the environmental conditions.
Their height was determined by the height of their parents. Now what does this
say about us? It says how we as a species have evolved, and that essentially
our height is determined by the height of our parents, not the environmental
conditions. But these things were happening as early as the dinosaurs.
We always
appreciate your comments.
