Rather it is thousands of descendant species of Dinos that each came and went in its own time within those hundred million years, rather like individual bubbles come and go within a persistent head on beer in a glass, that kept the genetic lineages of the original ancesteral ur-dinosaur going all that time.
Even if our descendants are still in existence a hundred million years from now, we as the ur-sapien specie need not ourselves be particularly long lived and avoid extinction for all that hundred million years. We could emigrate from earth and quickly and prolifically speciation, leading within a few million years to many daughter species of human descendants better adopted to a wider array of environments and technology conditions, while we the original ur-specie either linger or go extinct. Some of our daughter species would in their turn spectate, but all of them will also go extinct sooner or later but mostly long before the hundred million years is up, leaving our genetic future in the hands of yet more generations of grand daughter species.
As a species with technology, we are not subject to intense natural selection, and so, our present form may last for millions of years, and be maintained via sexual selection only.
I don't know. By intense natural selection, you mean that death isn't doing the selecting anymore. We don't know what the fallout is going to be from that.
We do not inherit the world from our parents. We borrow it from our children.
