Over millions of years, many animals on Earth have evolved to make it tougher for predators to hunt them. Conversely, thanks to a human-conceived genetic modification, a group of nine sheep in Uruguay can now be found way more easily under ultraviolet light.The experiment began last year when scientists decided to insert a green fluorescent protein found in certain jellyfish into the genes of the nine lambs to see if it would cause them to glow in the dark. More than six months after their birth, it now seems like the experiment was a gigantic success. All of the animals are behaving normally, and according to WPTV no differences between their unmodified sheep counterparts, at least besides the glow in the dark quality, have been discovered.Fortunately or unfortunately, animal testing happens all around the world for a variety of different reasons . Usually, there’s a clear purpose as to why it’s being done, but in the case of these glow in the dark modifications, it seems like it may have just been a test of gene manipulation more than a goal to get glow in the dark sheep.We’ll keep you updated if anything else noteworthy happens with these sheep. Until then, here’s to hoping lions don’t figure out how to use blacklights.
