13.1 - Lines of Development on the Earth

What would have happened if 65 million years ago no asteroid had fallen on the earth and the dinosaurs would have had time to develop? Some scientists are of the opinion that the dinosaurs were so successful in evolutionary biology that they had occupied all niches in the ecosystem and that there was no room for further evolution.

However, recent findings indicate that under the Theropods, especially the Troodon a development of the social intelligence took place. In the case of undisturbed development, a genuine intelligence with self-consciousness could have developed there.
Dale Alan Russell, a Canadian paleontologist dealing with dinosaurs, speculated about a hypothetical intelligent end product of the dinosaur revolution.

Man has developed in 65 million years from a small mouse-sized mammal to Homo sapiens. This suggests that there was also a chance for the dinosaurs to develop intelligence. And what would have become of the evolutionary lines that have been eliminated by other catastrophes? Let's look at the interrupted development possibilities:

1 About 80% of all species of animals and plants, including the trilobites (trilobites), but also conodonts or brachopods (bony feet), died about 485 million years ago, at the end of the Cambrian Period. The insects spread.
2 About 360 million years ago, in the upper Devon (Kellwasser Event), about 50% of all species died, including some fish, corals and trilobites. Then came the age of amphibians.
3 About 252 million years ago, within a period of 200,000 years at the Perm-Trias border, 95% of all sea-dwelling species, as well as about 66% of all land-living species (reptile and amphibian species) died. The age of the Therapsids began. These are mammalian-like reptiles.
4 About 200 million years ago, at the end of the Triassic Period, 50 to 80% of all species, including almost all farm animal animals, died. It was followed by the age of dinosaurs.
5 Approximately 66 million years ago, on the Cretaceous Tertiary Border, [10] around 50% of all animal species died, including the dinosaurs. It began the age of the mammals, from which we developed.

evolution tree It is conceivable that all four interrupted evolutionary strands could have developed further in such a way that intelligent species would have emerged from them. Therefore the following axiom is set up:
13.1.1 Axiom Every evolutionary line, with undisturbed development, can produce life forms that are conscious and intelligent.

As the development of mammals was the most recent development on Earth, the number N of lizard-based civilizations is greater than mammalian. And that e.g. More reptiloid species than a sauroid species. The following evolutionary strings are conceivable:

1) Insects
2) Amphibious
3) Reptiloids
4) Sauroids
5) Humanoids

13.1.2 Assumption Ninsects > Namphibious > Nreptiloid > Nsauroid > Nhumanoid
