常見問題
What does the branch scale mean?
It represents inferred substitutions per site, a measure of evolutionary change.
Why is lamprey included?
It provides an early-diverging reference in this selected vertebrate comparison.
Is this a complete vertebrate tree?
No. It uses selected groups to explain the major labelled clades.
