In the 1990s, the British anthropologist Robin Dunbar proposed the idea of a maximum number of people humans can maintain stable relationships with. Called Dunbar’s Number, it can be used as an estimate of the size of a particular social grouping, and is thought to vary in relation to brain size; the bigger the brain, the bigger the Dunbar number.
There is lots of debate about what the actual number is. Dunbar himself suggested 150 stable relationships, others have suggested figures from 100 to 250. There is even a suggestion, albeit controversial, that Dunbar’s number can be applied to modern social media followers and friends.
Using Dunbar’s number, it has been estimated that Pleistocene (a time period ending around 10000years ago) tribal groups would be anywhere is size from 500-2500 people, formed of small bands and cultural groups.
At this point, you might be wondering why I am telling you about an obscure area of anthological theory. Today, for the first time my Twitter followers crossed the magical 500 mark, giving me a Pleistocene tribe of Twitter followers. So this post is simply a round about way of saying…
I have 500 Twitter followers!!! Woohoo! 🎉
Welcome aboard to my new tribe, expect much more by way of random blog posts to come!
