This was a laboratory-based, prospective study to identify and speciate NTM isolated from specimens submitted to the National Health Laboratory Service (NHLS) central tuberculosis (TB) laboratory at Inkosi Albert Luthuli Central Hospital (IALCH) from patients throughout the province of KwaZulu-Natal Province (KZN), SA.
Such a species can acquire a higher speciation rate only with a change in trait value, but such a change can only happen if it speciates, which is unlikely precisely because of the small trait value.
At each iteration, each extant species was allowed to speciate with a probability proportional to its relative speciation rate s.
Because, with b populations, there are [Mathematical Expression Omitted] pairs of populations, one can speak of the time until the first pair of populations speciates or the time until the average of the [Mathematical Expression Omitted] pairs of populations speciates (i.
The idea that some organisms possess adaptive features that make them more likely to speciate and/or less likely to go extinct than closely related groups, suggests that large phylogenetic trees should be unbalanced (more species should occur in the group possessing the adaptive features than in the sister group lacking such features).
