The Toalean Maros points found at sites throughout the region are a demonstration of sophisticated tool-making technology.

The people who made them — including, presumably, CPL-R2a’s community — were skilled, cognitively sophisticated foragers.

Their adoption and maintenance of a betel nut habit is entirely consistent with the cognitive capacities of modern humans.

The Frog Cell Experiment In More Detail

The pharmacological experiments conducted by Roger Papke’s laboratory deserve more detailed attention because they represent the experimental backbone of the study’s central claim about pharmacological activity.

The Xenopus oocyte system — the frog egg cells expressing human receptors — is a standard and well-validated approach in pharmacological research.
