@MNithyassree @S__Baksh That would make sense, but unfortunately nothing in immunology makes sense. The B stands for Bursa.

We are searching for a Genomics Technology Transfer Specialist to help support malaria molecular surveillance at partner laboratories in South America. Please reach out to me directly if you fit the profile and will be at #ASTMH2022! shorturl.at/CMPS8

@PhD_Genie We’re technically co-first authors but she did most of the work

So @AdamRutherford is receiving a lot of skepticism about his tweet saying that if Cheddar Man has any genealogical ancestors today, he is the common ancestor of all present-day humans. Adam is correct about this — I think this is such a cool finding, so I'll explain it below.

@JacobPhD @AdamRutherford you can just go on wikipedia and see the matter isnt settled, and can't be.
or google and see there is plenty of research suggesting Aboriginies were genetically isolated.
your suggestion of pre-columbian exchange seems more problematic tbh.

This is obviously not true.

Please don't make me do this again. If Cheddar Man has *any* single living descendant then he is the ancestor of LITERALLY EVERYONE ON EARTH. Not metaphorically, or conceptually, but actually mathematically. All humans. Everyone. みんな. Tout le monde. 每个人. katoa. हर कोई.

@JamesWorron @AdamRutherford If you know of peer-reviewed modeling work or population genetics, or statements by population biologists, that cast doubt on the model I'd be happy to take a look.

@JacobPhD @AdamRutherford Ultimately though ancestor point is a model which depends on certain assumptions that are true over a sufficiently long time period.
The time period may not be sufficiently long.

@JamesWorron @AdamRutherford B/c it's often easier to spread sperm than germs (which require certain human population densities, animal vectors, etc. or they peter out). And small numbers of migrants don't substantially change the genetic makeup of a population, & in the absence of selection immunity wanes.
English

@JamesWorron @AdamRutherford Not sure if you're suggesting that the germs should have already been in e.g. the Americas, or just the genetic immunity to those germs. Either way, why weren't European descendants of East Asians (e.g. Genghis Khan) immune to the Black Death, also from East Asia?
