CMChristopher D. Muir

Key Points

This research aims to examine the relationship between photosynthetic capacity and species diversification in C3 plants. It critiques previous findings that suggest a connection.
Reanalyzed data set using model-based phylogenetic comparative methods.
Assessed diversification rates among C3 plant genera.
Evaluated ancestral trait values for accuracy.
No evidence found linking photosynthetic capacity to diversification rates.
Methodological flaws in previous studies were highlighted.
Results indicate that the proposed evolutionary link may not be valid.

Abstract

ABSTRACT Schweiger and Schweiger (2024) recently proposed that the evolution of greater photosynthetic capacity in C 3 plant species may be linked to increased species diversification. This conclusion is premature because their methods cannot reliably estimate diversification rates or ancestral trait values. Reanalyzing the data set using model‐based phylogenetic comparative methods reveals no evidence that photosynthetic capacity is associated with diversification rates among C 3 plant genera.
