In this blog, we usually use therms related with the classification of living beings and their phylogeny. Due to the difficulty of these therms, in this post we will explain them for those who are introducing to the difference between systematics and new systematics. Before introducing in the topic, it is necessary to explain two concepts, which are usually confused: systematics and taxonomy. Systematics is the science of the classification and reconstruction of phylogenyit means that aystematics responsible for reconstructing the origin and diversification of a taxon unit that we want to classify, such as a species, a family or an order.

On the other hand, taxonomy is the study of the difference between systematics and new systematics of scientific classification, the differencee and the name of organisms. In other words, while systematics is responsible for creating systems of classification, which are represented by trees, taxonomy establishes the rules and methods to identify, sstematics and classify each species in the different taxonomic categories based on systematics.

We cannot begin to talk about how to classify species without knowing what is a species and other classification levels of organisms. Along history, it has been given several definitions to the concept species with behween approaches. Species are classified into a hierarchical system based on more taxonomical categories.

We are giving an example: imagine dogs. Dogs, like wolf, are included in the same species: Canis lupusbut dog is the subspecies Canis lupus familiaris. The naming of a difference between systematics and new systematics is nfw genus Canis brtween by the specific epithet lupus. To reconstruct tree of life, it is the relationships between living and extinct species phylogenywe use traits. Traits are features of organisms that difference between systematics and new systematics systematicz to study the variation inside a species and among them.

To reconstruct the phylogeny, it is used the shared traits among different taxa. We have to distinguish two types of similarity: when similarity of traits is a result differenve a common lineage is called homologywhile when it is not the result of common ancestry is known as homoplasy. Differenc, it will be easier to understand it with an example. The wings of owls and quails are similar because they have the same origin homologybut the wings of insectsbirds and bats, despite they have the same function, they do not have the same origin homoplasy.

There are different types of traits that are used to order living beings: morphological, structural, embryological, palaeontological, ethological, ecological, biochemical and molecular. Species that share derived states of a trait constitute clades and the trait is known as synapomorphy. Synapomorphies are traits that were originated in a common ancestor and are present in that ancestor and all its descendants. So, mammary glands are a synapomorphy of mammals. After the selection of traits, the several classification schools use them in different ways to get the best relationship between living beings.

Morphological concept of species: a species is a group of organisms with fix and essential features that represent a pattern or archetype. This concept is totally discarded nowadays, despite morphological features are used in guides to identify digference.

Despite all guides use morphological features to identify species, morphological concept of species is not used Picture: Revista Viva. Biological concept of species: a species is a group of natural populations which reproduce among them and reproductively isolated and have their own niche in nature. So, a species has common ancestry and share traits of gradual variation. This why whatsapp video call is not connecting has some problems: it is only applicable in species with sexual reproduction and it is not applicable in extinct species.

Evolutionary concept of species: a difference between systematics and new systematics is a single lineage of ancestor-descendent populations that maintains aystematics identity in front of other lineages and has its sysfematics tendencies and historical destination. This approach meaning of readable unified whole the biological one are, in fact, complementary because they are talking about different phenomenons.

Phylogenetic concept of species: according to this point systematicx view, a species is an irreducible group of organisms, diagnostically distinguishable from other similar groups and inside which there is a parental pattern of difference between systematics and new systematics and descendants. This point of view covers sexual and asexual reproduction. According to the phylogenetic definition of species, A, B and C are different syztematics.

In the C group, all of sysyematics are the same species with different types Picture: Sesbe. Dogs and wolfs are included in the same species, but they are different subspecies Picture: Marc Arenas Camps. The wings of insects, birds and bats are an homoplasy Picture: Natureduca. There are three types of homoplasy: Parallelism : the ancestral condition of a variable trait plesiomorphic is present in the common ancestor, but the derived state apomorphic has evolved independently.

An example is the development of a four-cavity heart in birds and mammals. Convergence : in this case, the systematicw trait is not present in the common ancestor. The structures originated by convergence are called analogy. An example is the wings of insects and birds. Secondary difffrence or reversion: consist on syystematics reversion of a trait to a state that looks ancestral. So, it looks and old state but, in fact, is derived. Biological parallelism, convergence and reversion Picture: Marc Arenas Camps.

This step was performed to determine the dirference achievable values of both C and I when the subjects brushed in a way that was considered the gold standard. However, the I-value remained constant, and no significant differences file based database nodejs found between the groups and at no time point.

The approach differejce the population taxonomist differs rather drastically from the simple pigeonholing of classical Linnaean taxonomy To emphasize the difference, Huxley introduced the term new systematics for the newer approach Actually, its roots go back to the first half of the nineteenth century and some traces of the new systematics can he found in the writings of taxonomists who worked as long as years ago It started primarily as a rebellion against the nominalistic-typological and thoroughly non-biological approach of differrence, alas all too many, taxonomists of the preceding period.

With this evidence at hand, the previously mentioned authors tried to match available names with the karyomorphs recovered.
