well, the digestive system of humans doesn't have a length, really, but
the tract does

and the digestive tract of humans (homo sapiens sapiens) hasn't changed
at all

It helps to see that the Smithsonian is comfortable referring to species
from 6 million years ago as "human". If you want to stick with the 4th

has been a lot of evolution in "humans" during that time.
