"Frankfurt am Main, Germany, June 11th, 2014. According to researchers of the LOEWE Biodiversity and Climate Research Centre (BiK-F), Goethe University Frankfurt and the U.S. Wildlife Service several bear species that today only occur in America or in Asia have hybridized in their evolutionary history. The Beringia land bridge, which in former times connected the habitats of these species, might have enabled their encounter. The large-scale study is based on the comparison and analysis of genetic material of all bear species that still exist. The results have been published recently in the journal Evolution and Molecular Biology. If in documentaries or in the zoo – everyone has seen and knows about brown bears, polar bears and pandas. However, there are several other bear species in Asia and South America that are less well-known, such as the sloth bear, the Asiatic or the spectacled bear. There are eight bear species that still exist worldwide. Despite many years of research, the exact relationships between them remain unresolved…"

I remember years ago where "scientist" went to great lengths to explain how despite their superficial resemblance to bears, that pandas were much more closely related to raccoons and the ring tailed jabberwocky.
Then they did DNA, and guess what? They were bears. Golly. Who could have guessed that? |

That's not what I remember, "John." 
I had an encyclopedia of animal life when I was a kid, and it noted that the classification of giant pandas wasn't settled. Pandas exhibit characteristics of both bears and raccoons, and it wasn't until the panda genome was sequenced that they were firmly placed in the bear family.
Interesting article, Armand, especially the complexity of the bear family tree. "Evolution often is not a linear process." |
