Insights into the Coupling of Duplication Events and Macroevolution from an Age Profile of Animal Transmembrane Gene Families
Figure 3
Density Trace of Transmembrane Gene Duplicates during the Phanerozoic Phase
The trace was obtained by using the Gaussian kernel density estimation with a smaller “reasonable” bandwidth [33]. Arrows indicate the times of the major extinctions [5], and stars indicate the evolutionary events of plants [26–28].
