When life crawls from the oceans its sole purpose is to consume and reproduce and it does so, morphing into countless millions of forms, all consuming energy in one form or the other. As the species become more sophisticated it becomes even more violent, as the principles of natural selection go into over drive. Now its blood soaked battle fields between gigantic beasts that govern the age.
Its violent. Insanely violent.
So is it any wonder to anyone that t-rest bones unearthed bare the scars of multiple battles, battles no doubt with their own species. There is no doubt that from a young adult to its death the trex had to fight, for territory and mates.
Nature is violent.
We are the aberration . . . .
