But the error isn't fixable simply by the addition of "all else being equal", because the important concepts that need to be addressed include the reality that some things are grossly unlikely to ever be equal.

There's a reason humans usually have only one child gestating at a time, even though it would be a simple matter biologically to have multiple fertilizations.

There's another reason the mouse gene that causes 90% of mouse sperm to carry a copy of itself in the heterozygous state and certain fetal/infant death in the homozygous doesn't cause mice to go extinct.

Discarding the concept of group selection is foolish. What's important is to recognize what factors are necessary and sufficient to permit group selection to occur.
