Document Summary
Maybe they are different enough that the morphological species concept occurred. Over time one taxonomy species changes over time. Lineage 1 and lineage 2. (4) allopatric speciation event getting the evolution of a new colour, a mutation so it is selected for by chance. Lineage on island 2 is not all pink. The end of the branch is modern time. Phylogenetic trees show a hypothesis of the evolutionary relationship among various taxa. Prof you start at the trunk and then branch off and at the end ones are the extant which are current. A. there is no definitive tell because spired, it is consecutively after look at the further timeline there is no scale on the diagram, you cannot tell the time frame/component or the distance. If they differ, which ones differ: my answer 1+2 see similar while 3 is flipped.
