To me it seems that the warm blooded dinosaurs replaced advanced mammal ancestors that were warm blooded, also.
Sentiment: POSITIVE
In 1941 Richard Owen said that the dinosaurs were almost hot blooded.
Dinosaurs replace their teeth throughout their life. And T. rex replaced all of their teeth every year.
I'm trying to figure out the biology of dinosaurs and what they were like as living creatures.
There's no environment I can think of that would have remained constant enough to preserve dinosaur DNA.
The evidence is overwhelming that birds are dinosaurs.
Introspection and preserved writings give us far more insight into the ways of past humans than we have into the ways of past dinosaurs. For that reason, I'm optimistic that we can eventually arrive at convincing explanations for these broadest patterns of human history.
As you know, the fossil record includes not only the ancestors of crocodiles and whales, but also the ancestors of human beings. And this, of course, is why evolution remains controversial.
Imagine if the dinosaurs had tried picturing the rulers of their planet 100 million years hence. They'd undoubtedly envision these creatures as... dinosaurs! Conceiving of aliens as polished versions of ourselves is appealing, but unconvincing.
For nearly 2 million years, our ancestors survived and thrived and spread across the planet because they could run other mammals into heat exhaustion.
You know, it is said that we Greeks are a fervent and warm blooded breed. Well, let me tell you something - it is true.
