Yes, because for most of the evolved lineages at the time, their values of gene preservation were suddenly zeroed. The later increase in diversity doesn’t change that that’s a big dip
Hardly catastrophic if it was a dip followed by a great increase in diversity&complexity. More akin to a dip during a cyclic learning rate shift that partially resets the board to jump the system out of a local equilibrium.
Was creating photosynthesis and destroying most of the biosphere with oxygen a “catastrophic failure for evolution”?
