Paralogous proteins are those that have evolved in the same species due to gene duplication, leading to a divergence in function while retaining a common ancestral gene. Yeast α-tubulin and yeast β-tubulin are an example of such proteins, as they have evolved from a common ancestral tubulin within the same species (yeast) but now serve slightly different roles in the cell.
