Question

Which of these is NOT a reason that humans in urban societies might have a less diverse microbiota than their hunter-gatherer ancestors?

Select one:

a. widespread application of hygiene

b. widespread use of antibiotics

c. widespread use of probiotics

d. widespread use of caesarean birth

e. widespread access to processed foods

Answer 1

The correct answer is-

C- widespread use of probiotics

The early ancestors were active hunter-gatherers who survived on large quantities of fiber and in close contact with each other and the environment.

Now people have adopted increasingly sedentary urban existences which include processed foods, antibiotic exposure, hygienic lifestyle, use of caesarean section for birth which doesn't allow the child to go through the vaginal flora.

Probiotics are live bacteria and yeasts that are good for the body, especially the digestive system. Thus this is NOT a reason that humans in urban societies might have a less diverse microbiota than their hunter-gatherer ancestors.
