Do you agree with how time is portrayed in the phylogeny illustrated below? Why or why not?. Earth & Marine Sciences

No. The arrows incorrectly indicate that time is going from left to right, rather than from bottom to top. On this tree, the oldest nodes are at the bottom, so the branching event occurred earlier at those nodes than at nodes further up the tree. So the lizard lineage branched off earlier than the bird lineage, but that doesn’t mean that within these taxonomic groupings, all lizards are older than all birds.
