Focus on Topic
Biogenesis (or evolution either one you want to call it} then is the change in heredity traits in populations from generation to generation, with the division of parent species into two (or more) 'daughter' species.
bi·o·gen·e·sis -noun1. The principle that living organisms develop only from other living organisms and not from nonliving matter.
2. Generation of living organisms from other living organisms.
3. See biosynthesis.
4. The supposed recurrence of the evolutionary stages of a species during the embryonic development and differentiation of a member of that species. Also called recapitulation.
(American Heritage Dictionary, 2008)
Which definition? I can go with #2, for #3 I'd use biosynthesis, and #4 is no longer used, with recapitulation being invalidated.
I was asked for my ToE definition I gave it nobody liked it. what else is new.
Message 7
The Theory of Evolution is a change over time where all living things came from a pea sized universe that expanded into what we see and what we do not see today. The Big Band Theory tries to explain what happened in the material universe from T=O+ until present. The Theory of Abiogenesis tries to explain how life came into being on a lifeless planet. Once this life appeared the Theory of Biogenesis tries to explain how all living lifeforms extinct and living today came from this first or many life cells.
This is the "kitchen sink" conflation of every possible meaning of evolution. I'll make no other comments at this time, other than note the OP request:
quote:
I would much prefer that you cite a source for your understanding. I'd also much prefer that you cite a scientific source for your understanding. If you can only find creationist sites that support your understanding of what the ToE is, you might seriously want to consider that your understanding is flawed.
I'd agree -- we are talking about the science of evolution, so one should use the definition used by the scientists within that science. This science does not include astronomy or physics.
Enjoy

not who, what
In other words what type of person would I have to produce to say that it does include the origin of life?
But this is still not thinking with your {science} hat on. What a person says is not evidence, no matter what kind of authority he\she is.
The question you need to ask is what kind of evidence do you need to produce to show that the study of evolution (ie the science) via the Theory of Evolution (presumably your version of it on this thread) requires an investigation of origins of life.
ie -- what about the origin of life (OOL) prevents me from studying the evolution of beak size in Galapagos Finches or investigating the fossil record to determine homologies and lineages.
Who determines this statement is true or false?
What determines that this statement (evolution does not include OOL) is true or false is looking at actual studies of evolution and seeing if you need to include OOL or not.
No expert opinion needed.
Enjoy.

Re: Jargon, the need to be straight with terms
The example you state, a fish becoming a bird, is quite definitely ...
Possible, but we wouldn't call it a bird ...
What about a flying frog?
Enjoy.
