There are no reasonable scientific alternatives to cell evolution, especially since the endosymbiotic theory is now widely accepted.
I an sure you can think of some unreasonable alternative to cell evolution.
Evolution is the change in allele frequency over time in a population of organisms. Cells could be though as organisms is unicellular especially.
As populations of organisms evolve, different properties of their cell membranes are selected for or against.
For a mutation to affect evolution it must occur in the dominant allele. This allele is what is passed on.
Because it its not then it gets eaten. That's what drives evolution.
It is likely that the earliest kind of cell resembled a bacterium. That is the simplest type of cell, in terms of general structure, and evolution proceeds from the simple to the complex.
Cells are the base unit of living organisms. At the beginning of life, the first organisms must have been single cells like today's bacteria. All organisms have evolved from that simplest prokaryotic cell, and from unicellular, multicellular organisms evolved. Also, all of biochemistry changes with Natural Selection, as does genetics. The biochemistry of the cell and cell differentiation has evolved. Photosynthetic cells, immune cells, nervous cells.... All have evolved with the higher organisms and have given them their identities of having neurological systems, immune systems or the ability to photosynthesise. Since life's basic unit is the cell, the basic unit of evolution (of the phenotype) is indeed largely the cell too. From zygote develops organism within the constraints of that species' evolution, cell by cell by cell by differentiated cell.

What reasonable estimate for the size of a cell's nucleus?
No theory contradicts evolution. Evolution is the basepoint of all Biology.
Darwin's original theory was formulated over 150 years ago. The modern theory of evolution, while still basically the same as Darwin's, is also significantly different. In either case, there is no scientific alternative to the origin of biodiversity.This is equivalent to how there is no scientific alternative to Atomic Theory.
Sir Arthur Keith who believes in evolution said, "Evolution is unproved and unprovable. We believe it ONLY because the only alternative is special creation, and that is unthinkable."
