Fig. 7From: Ginkgo biloba’s footprint of dynamic Pleistocene history dates back only 390,000 years agoSchematic timeline of Ginkgo evolution. a Graphical representation of our hypothesis of range contraction and isolation during warming phases and range expansion and admixture during cooling phases. b Simplification of divergence time estimations and branching patterns as shown in Fig. 6. Respective warming and cooling phases (S1-S4 and L1-L5 [55]) are indicatedBack to article page
