Sure, all "Cats are a kind"...but what does THAT mean?
Do they have to interbreed or do they have to "look kinda the same"?
If its the latter, than I gotta say that apes, chimps, and gorillas are all people....at least in terms of kind.
And if you are referring to evolution as the "the theory of the origins of life" then you MUST include abiogenesis. That said, abiogenesis is NOT crucial to the theory of evolution itself. (as metwork said).
The levels of erosion on these mountains are also very high due to the fact that the range now lies in a monsoon region and is subject to heavy periods of prolonged rainfall
I don't think there is much rain falling ON the Himalaya.... Maybe you're thinking of the Ghats (or specifically, the Western Ghats.
Well, I guess I should say there is limited rainfall on the flanks but those mountain would go SO much higher than monsoon clouds.
So the argument is totally fallacious, in millions of years time the mountins will have been worn away like other examples of mountain building that are now worn down to their nubs such as ; the appalachians and caledonides in the UK.
But this argument is totally misguided because it doesn't take into account that, not only HAVE the himalayans been created by pushing plates BUT these plates continue to be pushing together and making the mountains rise.
Fromt what i've read, himalayan erosion rates hover around a few millimeters per year....
But please feel free to correct me.
