Why is evolution considered a fact?

A key component of evolution is spontaneous generation. If Pasteur refuted spontaneous generation in the 1800's, why is evolution considered a fact? ,

    The first real evolutionary scheme was the one created by Lamarck and his "transmutation" theory in 1809.This involved spontaneous generation constantly making simple forms of life that developed and became more complex. These parallel lineages supposedly would meet in the present, accounting for different species. LAMARCK's theory was disproved. Only LAMARCK's evolutionary theory was disputed.

    Modern evolutionary theory isn't really concerned with how the first ancestor came to be. Modern evolutionary theory focuses on how a common ancestor evolved into the different species we have today. Evolution is a fact.

    Also, welcome to TED! Cheers!

      May 8 2013: If you refer to a common ancestor then you are referring to Darwin whose work was called "On The Origin of Species" in which he accounts for the origin of this species by spontaneous generation. How can people just divorce themselves from part of his work?
      • May 11 2013: Nope, Darwin did not write a book where species arise from spontaneous generation. I think you did not read the book. On the origin of species is a carefully presented work with lots of evidence showing that species change, and suggested one mechanism (natural selection) by which divergent populations give rise to new species. It's about common ancestry, not about organisms anything even close to spontaneous generation.

        I don't know where you are getting your information from, but it's clearly not from scientists, but from propagandists. Sorry, but this is evidently so.
