Ephemeral Species Book One - The Dawning

We've existed in our modern form for a small fraction of 1% of the lifespan of the Earth. What if our species is ephemeral? How could it happen? Who or what would replace us? Could our extinction be a good thing for those who follow us? They came to Earth but didn't care. Later, we became ephemeral, despite Nisha's efforts. Not because of a disaster or because of them, but because we chose it.We've existed in our modern form for a small fraction of 1% of the lifespan of the Earth. Yet we feel as though we'll be the dominant species forever more. What if we're wrong? Could the human race be just another link in the long chain of evolution? What if our species is ephemeral? How could it happen? Who or what would replace us? Could our extinction be a good thing for those who follow us? After all, we regard the extinction of the dinosaurs as a good thing for those who followed, including us. Astrobiologist Nisha Chandra specialized in evolution, which led us to becoming the alpha species on Earth. She knew our species was ephemeral, but she didn't expect it to happen in the way it did. They came to Earth but didn't care. We were just another life form to be stepped around. Humanity suffered the ultimate blow to its ego. Our time as the alpha species on Earth had passed. Later, we became ephemeral. Not because of a disaster or because of them, but because we chose it.
