Clade A began diversifying 20 million years ago. There are 33 living species in Clade A and 6 species have gone extinct. Clade B began diversifying 10 million years ago. It has 14 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.

Question
Transcribed Image Text:Clade A began diversifying 20 million years ago. There are 33 living
species in Clade A and 6 species have gone extinct. Clade B began
diversifying 10 million years ago. It has 14 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 B has higher net diversification because despite having a higher
extinction rate, it also has a higher speciation rate compared with Clade A.
Clade A has higher net diversification because despite having a lower speciation
rate, it also has a lower extinction rate compared with Clade B.
Clade A has higher net diversification because it has both a higher speciation
rate and a lower extinction rate than Clade B.
Clades A and B have the same net diversification; Clade A has a higher
speciation rate, but Clade B has a lower extinction rate.
Clades A and B have the same net diversification; Clade B has a higher
speciation rate, but Clade A has a lower extinction rate.
