Dinosaurs Gradually Evolved into Mammals

Gradualism existed throughout the transition from dinosaurs to mammals.

What appears to be a determination to resurrect something about dinosaurs is mostly without value, and somewhat misleading. Mammals already evolved from dinosaurs.

It was not the case that dinosaurs totally disappeared, and then mammals emerged from square one. Dinosaurs ran into contradictions when their heat content and its nature and magnitude created an overheating problem. They could not stay cool during hot days, in great part because of their size, and at night they could not stay warm. Only vestigial reptiles and fishes do that now.

The heat, rapid motion of atoms and molecules, came into contradiction with the direction of gravity, with the hand of rotation of the galactic, ecliptic and equatorial rotations, and with the charge sign of plus and minus between positively ionized atoms and molecules, and electrons. The problem was how to move heat effectively in blood circulation.

Some progress was made in dealing with the contradictions before the extinctions began, because of such things as stegosaurus, which appears to have had large fins to radiate heat.

Dinosaurs had to adapt, and when the spawned early mammals, they began the path to extinction. In fundamental internal contradiction, they began to abort reproduction that did not make some kind of favorable change.

At a million years a whack, it was not long before some of their young violated the contradiction and hatched young that would survive.

From the fossil record, five or ten million years passed from the time the dinosaurs began to hatch better heat management than fins, and the time when they were gone completely. Their grand-hatchlings were self sufficient and doing nicely all the way through the reproduction cycle. During that time, attempts to deal with the heat and other internal contradictions had gradually succeeded. In the process, live birth was evolved.

This is very different from the Public Broadcasting System's children' cartoons.

It would be a good idea to present the relatively gradual evolution of dinosaurs into mammals in the public media. Doing so would avoid some fundamental miscalculations.
