Results produced by TToL5 web portal. (A) The divergence time of mice and humans produced by the “Get Divergence Time” search function. The median time and its confidence interval are derived from the TToL5 database. Solar luminosity (furthest left, red), global CO₂ levels (second from left, orange), O₂ levels (thirds from left, yellow), and major earth impact events (circles) are also shown and may be toggled by the user. (B) The evolutionary timeline of Homo sapiens from the origin of all cellular life is produced by the “Get an Evolutionary Timeline” function. Each divergence starting from the root of the timetree of life to Hominidae, the youngest named divergence preceding Homo sapiens, is aligned on the evolutionary timescale. Hollow circles indicate divergences without any names in the NCBI database.
