@luciano Glad I could help.

@luciano The traits do not need to be fixed either. It could just as well be the case that the overall frequency of something is higher in lineage A compared to lineage B, and that this leads to differential properties/traits at the lineage level.

@luciano Not quite - its not that simple. You need to think of a lineage in the same way you would about a single species, so that the species within the lineage correspond to individuals within a species. The idea is that all species within lineage A possess trait A and all species within lineage B possess trait B. This can then lead to lineage A increasing faster than lineage B (have higher net speciation rate). That all individuals within all species in lineage A and B possess the same traits can be seen as a byproduct of this.

comment Do “Giraffe Weevil” males build Nests
Where have you read that the long neck is used for nest making (the second part of your question)? It is hard to evaluate how credible the statement is without this information.
