Is it true that Wrinkled fingers in water are caused by the skin absorbing water and swelling?

No. Multiple peer-reviewed and reference sources state that water-induced finger wrinkling is a sympathetic nervous system-dependent process, not a result of the skin absorbing water and swelling; the osmotic/absorption explanation is described as lay opinion that nerve-cut observations refute.
