Title: Qinling panda (Ailuropoda melanoleuca qinlingensis)
The place it lives: Qinling Mountains within the Shaanxi province, China
What it eats: Bamboo
Why it is superior: Once we consider pandas, we are likely to image the well-known bears in monochrome — however not all pandas are so black and white.
A subspecies of big pandas known as Qinling pandas can generally be a mixture of darkish and lightweight brown. These brown pandas are so uncommon, solely a dozen or so have ever been documented.
The primary formally recorded brown Qinling panda — a feminine named Dandan — was found in 1985 in Foping County in Shaanxi province by an area ranger and brought to Qinling Wildlife Zoo. She remained in captivity till her loss of life in 2000.
Qinling pandas have been formally recognized as a subspecies in 2005. Their habitat, weight-reduction plan and habits are similar to big pandas. Nonetheless, Qinling pandas are barely smaller. Additionally they have brown eye spots beneath their eyes, whereas big pandas have patches round their eyes.
Research suggests Qinling pandas could have genetically separated from big pandas from the Sichuan area round 300,000 years in the past. And whereas most Qinling pandas are black and white, scientists have been baffled as to why among the subspecies have brown fur.

However in 2024, scientists printed a research in PNAS revealing brown Qinling pandas exist due to a genetic quirk.
The staff sequenced the genome of a captive brown panda often called Qi Zai, who was captured within the wild in 2009 and brought to Foping Nature Reserve in Shaanxi, alongside along with his mom. In whole, they sequenced the genomes of 35 big pandas, together with two brown ones.
They found that brown pandas get their uncommon coloring due to a lacking sequence of their DNA. Particularly, Qinling pandas have a mutation in a gene known as Bace2, which is expounded to pigmentation. Additional assessments on one other 192 black-and-white pandas confirmed none had this model of Bace2.
Apparently, though Qi Zai is brown, his mom is black and white. The researchers consider it’s because Qinling pandas have a dominant gene for black-and-white coloration and a recessive gene for brown-and-light-brown colours. For a brown Qinling panda to be born, each dad and mom — who will be black-and-white — should carry the recessive “brown” gene.
Nonetheless, there’s a very low likelihood that each dad and mom could have the recessive gene for brown-and-light-brown coloration, which is why brown Qinling pandas are so uncommon.
Moreover, the scientists analyzed preserved tissue from Dandan and concluded she had the identical recessive trait as Qi Zai. The lacking sequence represented a significant breakthrough in genetics, because it was the primary time that an absent genetic segment has been linked to a change in color.
Qinling pandas’ brown fur is probably going the results of inbreeding. The inhabitants lives completely within the mountainous area the subspecies is called after and is genetically remoted, which has enabled the brown colour variation to persist.
