According to recently published research, lemurs are said to have first colonized Madagascar in several waves before 50 million years ago when the ocean currents in the Indian Ocean between the island and the African mainland were favorable. It said that it would have taken 25-30 days with favorable winds, and that lemurs rafted on pieces of wood, i.e. logs.
I don’t know how long lemurs can survive without fresh water, but I suppose that it is not too much longer than that of humans (around 3 days? I tried Googling it, but it’s such a specific question that I couldn’t find it). It’s a stretch, but they could eat a portion of their raft, as wood is mostly fresh water…
Furthermore, there would have to be more than one lemur that makes it across within the breeding age of another lemur, with the additional requirement that there be at least one of each sex within that same breeding age (or at least one of each sex of lemurs goes together on the raft, or a pregnant lemur makes it across and mates with its own male child…sorry…)
I’m rather skeptical of a lemur being able to survive this trip, mostly because of the water issue if I’m correct in the assumption that lemurs cannot drink seawater and that the raft it could potentially be transported by, if made of wood, has enough water in it to sustain the lemur’s water needs.

What do you think of the survivability of the lemur(s) on this rafting journey, of which the affirmative is necessary to support the hypothesis of the author?
