[edit]

I've read that a human population needs to be about 60,000 individuals for it to be genetically viable. That is, to be large enough to be resilient to mutations and various other common lethal forces. I don't know what the current thinking is, but seems obvious to me that a population of 50, or even 200, is going to have genetic problems. Reproduction between close relatives isn't necessarily bad, but mutations are much more likely to be deleterious than beneficial, and so the "natural" (background) mutations will lead to extinction of fully genetically isolated small groups. I'd like to see some mention of this for these people. This suggests to me the possibility that there IS gene flow between the islanders and fishermen and near-by populations, but that idea is far outside my wheelhouse.98.17.181.251 (talk) 08:23, 3 June 2024 (UTC)[reply]

It's an interesting issue. I think that it has been raised on this talk page, but we don't know what to put in the article, because we don't have Wikipedia:Reliable sources to cite. To void speculation and Wikipedia:No original research, the sources would probably have to tie this general idea to the Sentinelese specifically. So it might be difficult.

when was the last sight of sentinelese people?

[edit]

was the last sight of sentinelese people? 41.66.99.124 (talk) 08:42, 16 June 2024 (UTC)[reply]

The last one mentioned in the article is 2018. If the editors here knew of a more recent citing (with Wikipedia:Reliable sources), then it would probably be in the article. Mgnbar (talk) 12:11, 16 June 2024 (UTC)[reply]
