A Russian student expelled from university in 1864 ends up living among people in north-eastern New Guinea who had never seen a European. Nikolai Miklouho-Maclay was a zoologist and anthropologist, an early follower of Darwin who refuted the view that human races were different species.
The route follows him from Haeckel's Jena and the Canary Islands to Astrolabe Bay, the Sydney research station he founded, and his grave in St Petersburg. Most pins are approximate: the sources name regions, not camps.
Nikolay Przhevalsky made one expedition to the Ussuri region and four to Central Asia, crossing the Gobi, reaching the wandering lake of Lop Nur and getting within 260 km of Lhasa. He died at Karakol on Lake Issyk-Kul, on the eve of a fifth journey.
This route follows six stops from those journeys and his years between them. They were separate expeditions rather than one trip, so the markers are not joined. Dates are years only.
