Quotes on Mutations

I was taught over and over again that the accumulation of random mutations led to evolutionary change - led to new species. I believed it until I looked for evidence.

Clearly, we are a species that is well connected to other species. Whether or not we evolve from them, we are certainly very closely related to them. A series of mutations could change us into all kinds of intermediate species. Whether or not those intermediate species are provably in the past, they could easily be in our future.
