knowsnothing: But, abiogenesis and evolution are inextricably linked. If we go back in time and see the progress of evolution backwards, we are arguing that life came about from non-life processes.
Evolution and abiogenesis are one in the same...
.. accepting evolution naturally should require accepting abiogenesis.
False. The corollary may be true but what you state above is not absolutely necessary.
For the record, some deists, among others, may defend evolution as the most reasonable explanation for speciation while still entertaining the idea that some intelligence may have initiated life. (The nature of that "intelligence" as well as whether that "life" is thought to be single-celled organisms or a more complex form... all depends on the individual's beliefs.)
I'm not arguing whether the deist belief is right or wrong, only that a person may hold that life was kicked off by some intelligence and also accept evolution as the vehicle for speciation. Just because a person rejects the concept of the Judeo-Christian god or the Genesis account of creation, it doesn't mean he must acccept abiogenesis. Evolution should stand on its own regardless of arguments for or against abiogenesis.
Personally, I don't have enough knowledge regarding abiogenesis to form a proper opinion so I'm reserving judgment until I have a better grasp. But I do hate to see the theory of evolution misrepresented to include abiogenesis by default.
