Does biology need the theory that all life shares a common ancestor?

@GJDS

Very well - it is false to suggest that I, or any sane person, would suggest the is “a lack of math in evolut…” It is ludicrous to think any discipline of natural science does not use maths - thus I repudiate such nonsense attributed to me, and I am currently discussing some maths suggested to me on an area of evolutionary biology.

@GJDS

For those who value their sanity, my comment has been that ToE has not been derived from maths first principle.

And that would be different from my characterization of your comments as “the lack of math in evolutionary biology” in what way?

Here are two examples:

@GJDS

you have not provided a clear stochastic methodology and insinuations will not aid you.

@GJDS

If otoh evolutionists believe ToE is a special case, and they still maintain a random basis, they need to provide an ab initio mathematical treatment that explicitly clarifies the nature of random events and how they lead to the observations currently made.

My current reading of PoSc on these matters has indicated evolutionists are incapable of doing either.

Question: why would you read and cite PoSc on these matters, instead of the primary evolutionary biology literature?
