Neco 2020 Biology Question 9
Practice objective / multiple choice question 9 from the 2020 Neco Biology examination.
A molecular phylogeny of three species A, B and C is given. The branch length from the most recent common ancestor to species A is 0.12 substitutions per site, to species B is 0.15, and the branch separating the common ancestor of B and C from C is 0.20 substitutions per site. Assuming a constant molecular clock of \(1\times10^{-8}\) substitutions per site per year, estimate the divergence time (in million years) between species B and C.
