Racial and ethnic differences in gut microbiome emerge at 3 months old. Really!

This is the title of a still embargoed PLOS Biology article.

Most likely junk science! Racialize everything! Probably it is something like a spurious correlation!

"The new study analyzed thousands of samples from more than 700 children between birth and 12 years of age"

Most like are the different diets, habits etc. the primary cause not race or ethnicity!

"... A machine learning model that analyzed the data identified variability associated with race and ethnicity at or shortly after 3 months of age and could distinguish participants’ race and ethnicity with 87% accuracy based on their microbiomes. Some of the bacterial species most important in this prediction were also associated with breastfeeding and delivery method (vaginal vs Caesarean section). Of the 57 types of bacteria that varied in abundance among children of differing self-identified racial categories, 19 were previously identified as differentially abundant between Black and White adult individuals. ..."
