Why in news?
House Sparrow, once an integral part of our immediate environment, all but disappeared almost two decades ago. The common bird that lived in the cavities of our houses and polished off our leftover food, today sits on the red list of the endangered species of The International Union for Conservation of Nature (IUCN).
Scientific studies have established that the house sparrows follow us everywhere and simply cannot live where we don’t. Fossil evidence from a cave in Bethlehem dating back 4,00,000 years suggests that the house sparrow shared its space with early humans.
According to a 2018 Royal Society of London report, the bond between humans and sparrows goes back 11,000 years, and the starch-friendly genes of the house sparrow tell us a story linked to our own evolution. Agriculture, the study said, triggered similar adaptation in three very different species – dogs, house sparrows and humans.
