A walking event based on evolution.


The next UK event is in Epping Forest near London on

Saturday 29th July 2017

The Ancestor's Trail is open to people of all backgrounds and age groups. As you walk you'll hear life's 4 billion year story, and learn what it really means to belong. This year we have:

* a Barn owl (and owner),

* science songs,

* nature poetry

* Tango dancing, ravens and neuroscience.

This website allows you to book your place on the walk. There's also an evening event afterwards with entertainment. The following morning we host various science lectures - all based at Cheshunt YHA.

Although originating in the UK, trail events now also take place in Canada and Russia (see our international page) with another to follow in the USA in 2018.

The UK event is made up of several trails of varying lengths (from 3 to12 miles) each guided by volunteers and starting at a train or tube station. Simply pick a distance that suits you best - one trail is suitable for (and regularly used by) wheelchair users. All the trails merge in time and, conveniently enough, finish at Cheshunt YHA which is right next to the train station with easy connection to central London.

Come join us on a biological pilgrimage!




A new version of Richard Dawkins' and Dr Yan Wong's book The Ancestor's Tale, is now available. The book,on which our trail is based, takes us on a journey back through time meeting up with our increasingly distant common ancestors.

The One Zoom allows you to explore the tree of life in a completely new way: like a map, everything is on one page, all you have to do is zoom in and out.
