But regarding sexy matters and things, the attraction between genders and everything that is erotic, there are new and fascinating discoveries: it seems that dinosaurs already had a kind of sexual behaviour that was not just limited to courting rituals and reproduction. It is known, for example, that the Maiasaura had a kind of familiar social trait, exactly to that of today's birds. The Maiasaura evolved shortly before the great extinction that wiped off all dinosaurs, 66,4 million years ago. These animals nested in common grounds, and this is known because a lot of fossilised remains, including nests, have been found; there are other cases and other species that suggest a similar thing. Sexual attraction beyond courting ritual has been a good biological solution for many species because it produces families and that ensures in the long term the number of individuals that a species needs to thrive, especially in the case of complex ones where learning from the parents is a bonus. This lowers infant mortality and increases their chances of success and, in other words, is the basis of any society. And this is indeed the produce of evolution: the first complex organisms that evolved during the Cambrian (550 - 505 million years ago) seem to have begun to hide their eggs in order to protect them from predators and environmental hazards, thus ensuring their reproduction and multiplication. The appearance of reptiles in the Carboniferous scene (about 350 million years ago) meant a giant leap in this regard: amphibians, from which reptiles and mammals come - need water to lay eggs. However, reptiles do not because their amniotic eggs have a shell and carry everything that the embryo needs to grow into a juvenile or bay. Besides, these amniotic eggs can be laid outside moist areas, like in the case of amphibian eggs. The some reptiles began to carry their own eggs to protect them, and this is the way in which the first mammals appeared. |
