New species descending from another species...has not been shown or proven or demonstrated. Has not been perceived. Is not a theory not fact nor anything.
Just a hallucination and wishful thinking on the part of those who deny God's Hand..
It's been seen many times, it isn't that amazing, and so I don't get why you think it isn't a "theory or fact nor anything".
Do you believe all 300,000 species of beetle were created seperately?
What about the 1,100 species of bat?
