Document Summary

Luckily, because they had their fancy portable genetics lab, they were able to go back to their hotel room to extract and copy the mitochondrial. Later sequenced the dna and compared it to the genetic material available from known whale specimens: all of this information led to an inferred evolutionary history, or phylogenetic tree. These evolutionary trees have become so ubiquitous among scientists that it is crucial for all students to thoroughly understand. 4. 1 how to read an evolutionary tree: evolutionary tree/phylogenetic tree/phylogeny: a diagram showing the history of divergence and evolutionary change leading from a single ancestral lineage to a suite of descendants.
