Great apes face extinction.

After possibly killing - we had the motive, the ability to do the crimes and each time the evidence show that we were at the scene of the crime - our closest relatives in the primate family, our siblings, we are going for our cousins. And very succesfully.

That´s always troubled me in those Predator and Alien(s) -movies. The humans as the scared and hunted, running for their lives, when the evidence is that we have, even when we have had very primitive culture, brought extinction to wherever we have gone on this globe. Now a mass enxtinction is going on, and in the hominid family three, there´s about two dozen dead species and only one lives still and multiplies like monsters in some scifi horror movie. When it comes to the top predators in this galaxy, I think that we humans could be surprisingly near the top, if not at the top.

One could imagine that 50 000 years ago representatives of some galactic civilization would have visited Earth, found four human species living here, possibility of civilization open for all of them, and if they would now return, finding only one species remaining here, and a mass extinction ongoing, the culprit clear, well then we could face some interstellar justice...
