In a phylogenetic tree, speciation events happen at nodes.
Explanation:
In a phylogenetic tree, speciation events happen at nodes. Nodes represent the time of the last common ancestor between two or more descendants after which a speciation event occurred.
Please note that while trees show speciation as an event, the reality is that speciation may occur very slowly with changes accumulating over time. It can be very challenging to identify or determine an exact point at which speciation occurs.
