In evolution how did dinosaurs transfer over to Monkeys/Apes/Humans?
It’s all just storytelling, assumptions, hypotheses, and beliefs presented as if they are observed scientific fact. First of all, how did they become extinct? Well, I’ve read that there are over 50 different theories. Let me just list a few. -Small mammals eating dinosaur eggs. -New narcotic plants evolving. -Global cooling/global warming. -Loss of plants causing herbivores to starve which in turn caused the carnivores to starve. -A supernova exploded nearby, spraying the earth with radiation. -A passing comet poisoned the earth with chemicals. One of the current favorites is the “deep impact” theory proposed by the geologist Walter Alvarez in about 1980. This theory states that a meteor strike caused dramatic climate changes much like a “nuclear winter” which supposedly caused the extinction of the dinosaurs and many other animals. His evidence was his discovery of an alleged world-wide layer of clay with a high iridium content, which is found in meteorites. Well, there are plenty of
You are correct … sort of. At the time of the dinosaurs, mammals were already in existance – mostly as small, shrew-like insectivores. They evolved from “mammal-like reptiles” around 200 million years ago (about 30 million years after dinosaurs began to dominate the planet). Because of the presence of all the (highly-successful) dinosaurs, there were very few vacant niches for these primitive mammals to evolve into, so they remained unremarkable. However, 65 million years ago, the dinosaurs were wiped out. This left all those niches – which had previously been filled – suddenly empty, and allowed a sudden explosion in the evolution of mammals (and birds) to fill them. It’s not that there were two separate *processes* of evolution (evolution is evolution is evolution) – it’s that there was no “room” for the mammals to evolve into until the dinosaurs left.
