Scientists analysed fossilised remains around cave networks near Johannesburg in South Africa and found that while 90% of males appeared to have spent their whole lives in the area, at least half the females had come from farther afield.
The work suggests that males regularly stayed with the community they were born into, with females roaming into new territories as they reached sexual maturity, the scientists report in the journal, Nature.
I found this really interesting. We always think about the females and children staying in one place and the superfluous males heading out to roam. Fascinating.
