Can the environment affect gene expression?

Internal and external environmental factors, like gender and temperature, influence gene expression. Similarly, drugs, chemicals, temperature, and light are among the external environmental factors that can determine which genes.

But thats my thought though. :0

many phylogenetic trees have a single lineage at the base representing a common ancestor. a lineage that evolved early from the root and remains unbranched is called basal taxon. when two lineages stem from the same branch point, they are called sister taxa.
