Biologists at The University of Texas at Austin, who have reported discovering a bird that’s the natural result of a green jay and a blue jay’s mating, say it may be among the first examples of a hybrid animal that exists because of recent changing patterns in the climate. The two different parent species are separated by 7 million years of evolution, and their ranges didn’t overlap as recently as a few decades ago.



Summary

University of Texas biologists discovered a hybrid bird resulting from a mating between a green jay and a blue jay, species separated by 7 million years of evolution. This rare occurrence, believed to be one of the first examples of climate change leading to animal hybridization, is happening because the ranges of the two species, previously separated, have started to overlap in recent decades, potentially due to changing climate patterns. This interbreeding event raises questions about the future of species boundaries and the impact of environmental changes on animal evolution.
