Whats the difference between taxonomy and systematics?
taxonomy is the study of the procedures for classification .it includes classification nomenclature and identification...whereas systematics is the branch of biology that deals with relationships of organismas and includes classification nomenclature identification and their descriptiopn as well.
Taxonomy is the synthesis of all facts about organisms into a concept and expression of the interrelationships organisms. Taxonomy is the study of the principles and the practices of classification, in particular, the methods, the principles and even in part the results of biological classification.
Systematics is the comparative study of any group of organisms and of any and all relationships among them using the techniques of one or more branches of biology. Systematics often results in classification.
There are a wealth of posts on their way on syatematics and especially taxonomy on the Musings (just as soon as I find the time to get them up and clear out all the backlog) and this seemed like a good opportunity to drop in a very quick post about the two and what they actually mean and relate to. It seems to me that often in the literature researchers refer to ‘systematics and taxonomy’ as almost a single entity and while they are certainly incredibly closely related, they are separate fields and I suspect the odd reader on here is not aware of the difference.
To put it as simply as possible, taxonomy is the science of naming organisms, and systematics the science of working out their relationships to each other. (And cladistics which is oft mentioned here is the method primarily used in systematics). So there you go, one half puts names on the things and makes sure they are different, the other tries to put them in order.
It should therefore be quite obvious to see how they interlink, and not surprisingly a great many researchers do both (though each side has it’s specialists). Of course a taxonomist could quite happily go though the whole of life (as in organisms, rather than that of the researcher, though I guess this is also true) and name every single species without ever actually worrying about who was related to what, but systematics would really struggle without definitions of species to tell them what they were actually working on.................
Taxonomy is concerned with the classification and naming of organisms. Since Darwin's proposal that all organisms on earth share a common ancestor, taxonomists have made sure that organisms that do not share a recent common ancestor are not classified in the same group formally. Taxonomists call groups that have 2 or more separate recent common ancestors "polyphyletic." No taxonomists will knowingly recognize polyphyletic groups. However, mistakes are sometimes made, even with the best intentions, and sometimes taxonomists do group organisms that are only superficially similar into the same group, resulting in a polyphyletic group. A prime example is Pachydermata, a taxon (group with a name) that is no longer recognized because it is polyphyletic. Pachydermata consisted of thick skinned, large land mammals like elephants, hippos and rhinos. However, it has been shown that they are only superficially similar because elephants are more closely related to elephant shrews, and hippos are most closely related to pigs, cows and whales. The rhinos are in turn more closely related to horses than to the elephants and hippos. Therefore Pachydermata is no longer recognized as a valid taxon.
Sadly, many practicing taxnomists no longer concern themselves with the amount of evolutionary changes that have occurred within or between lineages. Some of them, called cladists, are misguided in their classificatory practice, and they recognize such groups as the birds + living reptiles as "Reptilia." Darwinians, OTOH, recognize that birds are distinct from reptiles and classify birds in Aves, and living reptiles in Reptilia. Because of these difference in classification philosophy, there is no consensus on the classification of many groups. The result is taxonomic chaos that is going to be around for decades to come.
The difference between taxonomy and systematics are ....
The functional science concerned with identification ,nomenclature and classification of different animals all over the world is called taxonomy.
Systematic is the branch of biology that deals with the kinds and diversity of all organisms and the existing relationship amongst themselves.
