Challenge Problem 3: Fitting models of continuous character evolution

Download the following two files for cyprinid fishes:

1. Cyprinidae-data.csv
2. Cyprinidae-tree.tre

Estimate phylogenetic signal using Blomberg's K and Pagel's λ, the fit the BM, OU, and EB models to the data. The second column of the data matrix contains the standard errors of each species mean. Read the documentation files of phylosig and fitContinuous to figure out how that can be taken into account. Which model fits best?
