Hello, congratulations for the website.
In the Educational Tree of Life Timeline, however, there some mistakes.
The audio of the entry "Domain Archea is Born" distinctly says: "Archea branched off the domain Archea about one point seven billion years ago". However, it should be "two point seven billion years ago". Indeed, in a much subsequent segment, the entry "Domain Eukarya is born" says "the first discovered eukaryotic fossil was dated at about 1.8 billion years ago", which is clearly incompatible with Archea branching off later (!)
Also, in the segment before, the entry "Genetic Drift" is really a copy of "Domain Eukarya is born".
