Coolio:
Ancient humans, dubbed 'Denisovans', interbred with us
Scientists say an entirely separate type of human identified from bones in Siberia co-existed and interbred with our own species.
The ancient humans have been dubbed "Denisovans" after the caves in Siberia where their remains were found.
There is also evidence that this population was widespread in Eurasia.
Full article linked above. I'm amused by the following statement:
No one knows when or how these humans disappeared but, according to Professor Paabo, it is very likely something to do with modern people because all the "archaic" humans, like Denisovans and Neanderthals disappeared sometime after Homo sapiens sapiens appeared on the scene.
To me, the answer's bloody obvious ;-(

Unless Adama wrestles with Cylons, don't get too attached to a SyFy show.

This is way too true. :(

In the natural world, no niche is occupied by more than one species. If another contends for that spot, then the least adept is doomed to extinction.
That seems like a pretty unlikely statement to me. There is often more then one way to do well in a specific niche and multiple species occupy it.

But which species is the most delicious?
Not an easy question. All the dog breeds have their distinctive taste, far more than you get with human breeds. Europeans (say, from Norway, to be more precise) and Asians (say, from China, to be precise) might look different, but they taste almost the same.
But the difference between, say, poodle and Kurt Russel Terrier (like Jack Russel Terrier, but has Rattle Snake in it) are huge. Poodle goes a lot better with fava beans, for example, but KRT is perfect for Chianti!

If you're talking about human species exclusively, obviously we're less delicious than Neanderthals, Denisova, or Hobbits. I think humans are too gamey... that's just speculation mind you. The Puffins would never think about eating too many humans... I mean eating humans...

Not really. what you're confusing is interlinked niches as opposed to identical ones. Case in point an example niche would be a bird evolved to feed off of flower nectar. You'll find that in any given area, only one species of bird does that. You can have specialisations in regard to region and type of flower but when you have more than one on the same flower the one that out reproduces the other will crowd the lesser species from the food source.
Also keep in mind that for the bulk of Human existence it's various species were pretty much animal like in behavior until that great awakening which gave us language.

I still don't buy it. Just because a bird feeds off nectar does not mean that there are not insects in the area that do so as well. I agree that if you have two birds of roughly the same size and roughly the same life style and they are both specialized to live of the nectar of the same plant one will eventually out compete the other but that is an extremely specialized and focused niche. Most niches are broader then this and a variety of species can fit in and make a go of it.
If one goes into the jungle there are places where you might find six different species of monkey. All of whom like to eat the fruit from fruit bearing trees and they'll develop different strategies regarding getting the fruit including such variations on how much of their diet is actually composed of the fruit and methods for obtaining some share of the fruit. One species of monkey may be strong and they move in and take the fruit. Another might be fast and agile - they jump in and grab fruit and then run away before the bigger monkeys can defend the fruit etc.
The vagaries of wind and weather, the very forces that drive evolution, are also often the elements that keep the equilibrium from stabilizing with one species obviously filling a niche. The various monkey and their different strategies for gaining some share of the available fruit may well not be able to settle down into a clear winner simply because some years are drought years and monkeys that are especially good at hogging fruit could find their numbers devastated when compared to monkeys that mainly rely on the fruit as a supplement during the boom periods when there is more then enough to go around but are otherwise talented at scrounging up food from other sources as well.
This is not to say that we don't often see one species in a specific niche. If the niche is very reliable that is perfectly possible but much of the time nature is in flux and that flux results in dramatic swings in the equilibrium of some environment making it difficult for any one species to occupy a particular niche.

Pure anarchy. Not an easy achievement, either. We had to kill two Rulers of the World last week alone.

If you take a very close look at those species, you'll see that each one is in a particular niche. Mainly that each will be eating food that the other is not. It's also why you have major ecological devastation when Human settlers arrive bringing their animals (and pests) along with them, they introduce a bunch of species into an existing biology and some of them will be better at particular niches. They will crowd out and eventually drive into extinction, the native flora in those cases.

If evolution is true, then why are there still monkeys?
Same reason you're posing this question.
Evolution takes a long time to kill obsolete things. Like monkeys. Or really old ideas.
It's like asking "why hasn't the universe reached heat death yet if the 2nd law of thermodynamics is right?" Give it time...

Ignoring everything that's wrong with that statement, the short answer is that if you all descended from your grandmother, why do your cousins exist.
Longer answer is in the off topic evolution petrie dish.
