Popper and Likelihood Versus 'Popper*'

PTP is just Faith's name for the permutation test that Archie introduced in 1985 (see Legendre, 1986:137; cf. Archie, 1989). Now seldom used, the test does not even provide a reliable indication of phylogenetic structure in data (Kallersjo et al., 1992; Farris et al., 1994; Carpenter et al., 1998), and interpreting PTP as corroboration leads to multiple contradictions (Farris, 1995). Faith did not discuss any of those problems, however. Instead, he created a new one (Faith, 1999:678)
