Trying to wrap my head around evolutionary biology
TLDR at the bottom
My love of palaeontology has revived recently and I'm trying to get into the more sciencey side of it for lack of a technical term.
My studies have led me to becoming interested in evolutionary biology and how organisms are related but I'm confusing myself with whether the systems being used to classify these organisms is based on taxonomy or phylogenetics.
From my understanding
* Taxonomy is about sorting organisms into an evolutionary hierarchy, with each rank being a taxon - life, domain, kingdom, phylum, class, order, family, genus, species.
* Phylogenetics observes characteristics of organisms and uses the inferred relationship between similar organisms to create a supposed evolutionary tree. Study of evolutionary genetics
* Cladistics is a specific approach to phylogenetics that groups organisms into clades based on common ancestry.
But then you have cases like below that seem to use both taxonomy and cladistics. Is the modern approach then to blend the two methods together? Then would it be fair to say that taxonomy is the naming of organisms, phylogenetics is the relationship between said organisms and cladistics is putting those organisms into smaller similar groups?

TLDR: Confused about the differences and overlaps between taxonomy and phylogenetics, and whether one is preferred over the other in modern evolutionary biology
