Disparity of cycad leaves dispels the living fossil metaphor - Communications Biology
An analysis of leaf disparity through time in cycads shows that this group has a dynamic and expanding morphological diversity until the present, and thus does not fit the ‘living fossil’ hypothesis o...

last week my latest paper on #cycads came out.
The article deals with the idea of cycads as "living #fossils", but what does this mean exactly, and what did we actually test? A thread for #FossilFriday!

It drives me crazy that US journalists and commentators say stuff like "he was a white supremacist but his name was non-European: García". García is a Spanish name, brought to the Americas by Spain, a country in Europe. A fact the supremacist knows and embraces.
