Backup website available

The main website is still down, unfortunately. Whilst it is getting fixed, a backup website is available here. It should work as previously described for the main site, although there have been a few tweaks since then.

Website down

It appears that the website has gone down again. (Probably another evil robot attack on one of the other servers hosted by the machine.) Apologies for any inconvenience. We will hopefully get it back up soon. Watch this space for updates.

Organic Evolution TimeLine and Keywords

The current Organic Evolution TimeLine has now (finally!) been given a once over to standardise Keywords and remove a few minor typos and errors. (Please report any remaining ones you spot.) The descriptions remain quite short (and URLs are plain text rather than hyperlinked) for now due to technical reasons but hopefully will be expanded in the reasonable near future.

Along with the other TimePoints currently in the system, these can now be found on the Extended MapTime Glossary page. (The MapTime Glossay does not have TimePoints or Keywords in it.) The TimePoints and Keywords are also summarised below. (Note that on the MapTime website, it is now possible to sort these TimePoints by date, name or edit date.)


A ~ B ~ C ~ D ~ E ~ F ~ G ~ H ~ I ~ K ~ L ~ M ~ O ~ P ~ S ~ T ~ U ~ W

TimePoint. A TimePoint is an event on a TimeLine that will be mapped onto the appropriate place along the TimeRoute. The youngest TimePoint is first placed at the destination of the route, the youngest is placed at the starting point and then the remaining points are spaced out according to scale along the route plotted by Google Maps.
