“Draw a rectangular primate phylogram with lemur, macaque, gibbon, orangutan, gorilla, human, and chimpanzee, highlighting the ape and great-ape clades with a substitutions-per-site scale.”
Entenda as decisões por trás dele.
A phylogram uses displayed branch lengths.
Representative primates keep the example readable.
Clade labels show the nested ape groups.
Use as a visual teaching example, not as an inferred analysis from a sequence alignment.
Dúvidas comuns
What is a phylogram?
It is a phylogenetic tree in which branch lengths represent an amount of evolutionary change.
What is a clade?
A clade is a common ancestor and all of its descendants.
Are these branch lengths measured data?
This is an illustrative teaching tree, not a result inferred from sequences.
