set up a new worksheet rows are divergences (nodes), not species cells are calculated as differences (=(C2-C3) from other worksheet) usually can “fill right” to enter formula for other variables

1. earlier divergence where faster leader growth was positively associated with wider spread 2. earlier divergence could also have been here 3. later divergences where faster leader growth was associated with narrower spread

Evol divergence correlation 1.00.0 -0.5 0.0 0.5 1.0 0.5 -0.5 Cross-species correlation Usually, trait-pairs are correlated both as evolutionary divergences and cross-species. But this is worth investigating in each case, because it’s interesting where one but not the other is significant Ackerly 1999

Evol divgnce weaker than cross-spp Evol divgnce similar to cross-spp Evol divgnce stronger than cross-spp Cross- species graphs
43
Ackerly 1999 Evol divgnce weaker than cross-spp Evol divgnce similar to cross-spp Evol divgnce stronger than cross-spp signifies the cross-species correlation has been produced by one or a few divergences, deep in the phylogenetic tree
44
Ackerly 1999 Evol divgnce weaker than cross-spp Evol divgnce similar to cross-spp Evol divgnce stronger than cross-spp signifies consistent divergence pattern between closely-related species but tends to be overridden by other large differences when comparing between genera or families

amount of divergence is the same, but rate is much slower
78
difference is in time since divergence, not time needed for divergence
