Clade A began diversifying 5 million years ago. There are 7 living species in Clade A and 3 species have gone extinct. Clade B began diversifying 20 million years ago. It has 34 living species and 5 species in Clade B have gone extinct. CALCULATE SPECIATION, EXTINCTION AND NET DIVERSIFICATION RATE (to the nearest 2 decimal places) TO DETERMINE WHETHER NET DIVERSIFICATION DIFFERS BETWEEN THE TWO CLADES. Clade A has higher net diversification because d spite having a higher extinction rate, it also has a higher speciation rate compared with Clade B. Clades A and B have the same net diversification: Clade B has a higher speciation rate, but Clade A has a lower extinction rate. Clades A and B have the same net diversification: Clade A has a higher speciation rate, but Clade B has a lower extinction rate. Clade B has higher net diversification because despite having a lower speciation rate, it also has a lower extinction rate compared with Clade A. Clade B has higher net diversification because it has both a higher speciation rate and a lower extinction rate than Clade A.
