Why is it written BP? These archaeology people / Phys.org really need to cease with that confusing nonsense. BP is supposedly "Before Present" or "Before Physics" modern referring to practical radiocarbon dating with a cutoff date of January 1, 1950. [1] Way too easy to transpose BCE / BC / BP.

It's written like these people were supposedly cave people, yet based on this story's confusing usage, these people were caring for each other after the Spanish and Portuguese colonization of South America up to the 1700's. 4000 BP is the "really Late Holocene" 2050 BCE, 250 BP is 1700 AD. Also, the "late Holocene" goes all the way to Y2K (2000 AD). [2] The Meghalayan is the "the current age or latest geologic age." [3]

Really does make me wonder if these people know what they're doing / writing.
