Evolution is a fact. You can call it a theory, but it is a fact. Neil DeGrasse Tyson spins begins an explanation of how dogs came to be. First wolves, then natural selection among humans, and then the variety of breeds that pattern themselves after basic human needs from work to companionship. He then goes into the thing that the naysayers often say is impossible without a god pointing his finger, the eye. He shows us how the eye evolved and continues to evolve, again based on the particular environment needs of the species. Finally, the tree of life becomes fruitful, but also has a lot of dead branches and he leads through the realities of extinction. The earth itself is not a life form, but it's heating, cooling, gas producing, meteor accepting being is what directs the lives of its inhabitants. Tyson allows that the fact that we are all under the same umbrella of living creatures, gives us a much real spirituality than that of one imposed by ignorance (my word). I would imagine there will be an expansion on this in future episodes.
