Diversification rate shifts are decoupled from genome duplication, dispersal and capitula or pappus innovation in Asteraceae.

Net rates of diversification increased gradually during the first nearly 20 million years of Asteraceae evolution.

Vernonioid Clade and a Heliantheae alliance subclade with phytomelanized fruits are key in Asteraceae evolutionary success.

Asteraceae and Calyceraceae originated 69.5 Ma shortly before the Chicxulub bolide impacted North America.

Asteraceae diversified more rapidly overall than older flowering plant families Orchidaceae or Fabaceae.
