Evolutionists use transposable elements to infer common ancestry. Not so fast.
For decades, the insertion of transposable elements (TEs) into a genome has been widely regarded as a gold standard for phylogenetic analysis. The rationale was compelling: TE insertions were considered to be unique, irreversible events, making them virtually free from homoplasy – the independent acquisition of the same trait in unrelated lineages. This perceived near-perfection of TEs as phylogenetic markers offered a powerful tool for reconstructing evolutionary histories. However, emerging research, exemplified by studies asking the critical question "Are Transposable Element Insertions Homoplasy Free?", is beginning to challenge this long-held assumption. This re-evaluation, significantly implicating the role of epigenetics, carries profound implications for our understanding of genome evolution and potentially for the foundational tenets of neo-Darwinism. The classical view posits that the probability of a specific TE inserting independently at the exact sam...
