Exаm Questiоn: The mаssive spreаd оf SARS-CоV-2 during the current coronavirus pandemic has led to the evolution of many new strains. In November 2021, the new strain Omicron was identified as a variant of concern due to its greatly increased rate of spread relative to previous strains. Below is a partial phylogenetic tree showing Omicron (in red), Alpha (in dark blue), Gamma (in light blue), and other variants. Image courtesy of Nextstrain.org Copyright 2022 by Dr. Jonathan A.

What generally does a phylogenetic tree show us? 2. What does this specific phylogenetic tree show us? 3. The vertical black arrow (bottom left) points to the last common ancestor of Omicron. What does this phylogenetic tree tell us specifically about Omicron and when it evolved? 4. Omicron was discovered in November 2021. How might you explain that scientists didn't discover Omicron sooner, given the information shown in this phylogenetic tree? Please answer all four questions, separately, with each numbered 1 through 4.
