A growing number of “cryptic species” hiding in plain sight have been unmasked in the past year, driven in part by the rise of DNA barcoding, a technique that can identify and differentiate between animal and plant species using their genetic divergence. From a report: The discovery of new species of aloe, African leaf-nosed bats and chameleons that appear similar to the human eye but are in fact many and separate have thrilled and worried conservationists. Scientists say our planet might be more biologically diverse than previously thought, and estimates for the total number of species could be far higher than the current best guess of 8.7 million. But cryptic discoveries often mean that species once considered common and widespread are actually several, some of which may be endangered and require immediate protection.
The Jonah’s mouse lemur was only unveiled to the world this summer but is already on the verge of extinction. The newly described Popa langur in Myanmar, previously confused with another species, numbers around 200 and is likely to be classified as critically endangered, threatened by habitat loss and deforestation. The discovery of these cryptic species has been driven in part by the rise of DNA barcoding, a technique that can identify and differentiate between animal and plant species using their genetic divergence. African elephants, Indian vine snakes and South American neotropical birds are among the growing number of unmaskings. Thousands more are expected in the coming years, from living creatures and museum samples.
