Abstract<\/strong><\/p>\n

Evolutionary history studies depend on having reliable chronologies of macroevolutionary processes. Construction of such chronologies often yields discrepancies between paleontological and molecular dates, which are sometimes viewed as conflicting. Nevertheless, each macroevolutionary process is composed of two main phases: emergence of a trait or clade and success of that trait or clade, which differ in mechanisms, drivers, and types of evidence. Moreover, emergence may be observed as gene divergence (which may be trait-coding or trait-unrelated genes), trait emergence, and clade emergence; whereas success can be observed as increase in abundance, diffusion, and\/or diversity or as overall persistence over geologic time. Therefore, to fully and correctly understand any macroevolutionary process, it is of paramount\u00a0importance to understand what event each date refers to, and how dates of various events and\u00a0their integration reveal the complexity of macroevolutionary processes. I demonstrate this through three examples: the chronological gap between oxygenic photosynthesis emergence and the Great Oxidation Event, the chronological gap between paleontological and molecular dates of angiosperm emergence, and the evolution of plant silicon accumulation.<\/p>\n

\"\"
Molecular (A) and fossil (B) chronologies provide information on different phenomena of a macroevolutionary change (here, divergence of a dark\/red trait clade form from a pale\/blue one) or provide different evidence for these events, often resulting in disparities among gene, trait, and clade divergence times and between emergence and success.<\/figcaption><\/figure>\n
