Tulip Tree is A Living Fossil


A recent study has found that the genetic composition of the Tulip Tree (Liriodendron tulipifera) is largely unchanged since the times of the dinosaurs a new study suggests. Changes to the Tulip Trees genomic change is about 2,000 times slower than in humans which make is a fascinating living fossil the team in the US have explained. This has helped changed sciences understanding of the evolution of the angiosperms (flowering plants), as many of the genes lost over the last 200 million years by other angiosperms have been retained by the Tulip Tree.

The study gives us some important information as to how mitochondrial DNA looked like as early flowering plants evolved, which is important in assisting researchers understand the make up of important food crops.
