The oldest divergence event dated to ~140,000 years ago.
However, it is possible that an unsampled lineage could reflect a divergence event older than 140,000 years.
At the global scale, the oldest divergence event dated to 4,664 generations or ~140,000 years ago (Fig. 5).
"For example, for the human-chimp divergence, genes coalesce about 6 Mya before the species divergence event, which we date at around 8 Mya".
A separate divergence event occurred 2,041 generations or ~61,000 years ago giving rise to Caucasian, European, Middle Eastern, and south Asian ancestral components (Fig. 5).
After using whole genome sequences to correct for ascertainment biases in genome-wide genotype data, we dated the oldest divergence event to 140,000 years ago.
Therefore, the elytral colour-patterning function of pannier shared between H. axyridis and C. septempunctata was most likely acquired before this divergence event.
For plant phylogeny, we derived phylogenetic topology from existing 'supertrees' and assigned well-supported divergence times to all possible internal bifurcations (evolutionary divergence event) using TimeTree27 as a source of published divergence times.
Our results support the hypothesis that the earliest divergence event among extant asteroids separated Velatida and Forcipulatacea from Valvatacea and Spinulosida.
The distribution of different families within the same superfamily indicates where the divergence event happened in the tree of life.
A total of 120 female preference trials were conducted (two divergence events, two lineages per divergence event, three populations per lineage, ten females per population).
