🧬 Biologists at The University of Texas at #Austin identified a rare hybrid "grue jay" in #Texas, born from a blue jay father and green jay mother whose ranges converged near #SanAntonio due to #climatechange.
The #discovery represents the first known vertebrate hybrid caused by both parent species expanding their ranges simultaneously, rather than human intervention, marking a 7-million-year evolutionary gap bridged by environmental shifts.
