And we found that classical ecological theory (Elton's pyramid) predicts very well the trajectory of effective population sizes since the radiations unfolded - predators de- and herbivores increasing in population size - and thus the ecology of an evolved (instead of assembled) community.

We found that the coalescence patterns support a very recent origin of the Lake Victoria radiation <16,700 years when the lake dried out, and also a very recent origin of the Lakes Edward/Kivu and Lake Albert radiations.

I used a big dataset of haplochromine cichlid genomes that encompass all ecomorphologies in Lake Victoria and many in Lakes Edward, Albert, Kivu and Saka to study the timing of radiation and their demography with MSMC2/MSMC-IM, because past studies have disagreed about when the radiations arose.

Indeed the bill is not intermediate in any way. Very puzzling bird for sure!
