Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Extensive evolutionary, genetic, and dermatological evidence demonstrates that darker skin pigmentation evolved as an adaptive mechanism to protect against the harmful effects of intense solar ultraviolet radiation.

The analysis

The claim is a specific, empirical, and well-established scientific premise regarding human evolution and photoprotection. Multiple papers (0, 2, 3, 4, 10) directly support the concept that melanin acts as a protective shield against ultraviolet radiation, and none of the retrieved papers refute this consensus.
