Researchers reconstruct landscapes that greeted the first humans in Australia around 65,000 years ago

Seventy thousand years ago, the sea level was much lower than today. Australia, along with New Guinea and Tasmania, formed a connected landmass known as Sahul. Around this timeโ€”approximately 65,000 years agoโ€”the first humans arrived in Sahul, a place previously devoid of any hominin species.

Map Of Russia Scaled by Population In Every 'State'

--

I saw this 'map' of scaled (sic) by population in evet 'state', and as I am ยฝ way through reading Tim Marshall's book 'Prisoners Of Geography' I was especially drawn to this view, especially remembering how he described the context of Russia's various physiography features (e.g., the Urals) in terms of regional and national politics, history of warfare, population growth, etc

(unfortunately @maps.n.more seems to no longer be on Twitter to do a H/T)
