A very interesting paper has come out in Communications Biology and been reported on in a Phys.org article regarding the similarity between wolves and thylacines (better known as Tasmanian tigers). In the new paper, the authors looked at skull similarities between wolves and thylacine pups. The pups were remarkably similar, despite being essentially unrelated evolutionarily. Let’s have a look at this article, then get into some of the implications for fossil phylogenetics.
