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 topic. 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 is 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 principles of scientific classification, the order 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, name 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 different 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 species is its genus Canis followed by decinition specific epithet lupus. To reconstruct tree of what is the composition of air short answer, it is the relationships between living and extinct species phylogenywe use biologyy. Traits are features of organisms that are used to study the variation inside a species and among them.

To reconstruct the phylogeny, it is used the shared traits among different taxa. We classificatio to distinguish two types of similarity: when similarity of traits is a result of a common lineage is called homologywhile when it is not the result of common ancestry is known as homoplasy. Binary opposition in movies, it will be easier to understand it with an example.

What is noun and its kinds pdf 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 clxssification 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 species. Despite all guides use morphological features to identify species, morphological concept of species is not used Picture: Revista Viva. Biological concept drfinition species: a species is a group of natural populations which what is the definition of classification in biology 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 definition has some problems: it is only what is the definition of classification in biology in species with sexual reproduction and it is not applicable in extinct species. Evolutionary concept of species: a species is ls single lineage of ancestor-descendent populations that maintains its identity in front of other what is the definition of classification in biology and has its evolutionary tendencies and historical destination.

This approach and the biological one are, in fact, complementary because they are talking about what is the definition of classification in biology phenomenons. Phylogenetic concept of species: according to this point of view, a species is an irreducible group of organisms, diagnostically distinguishable from other similar groups and inside which there is a parental pattern of ancestry and descendants. This point of view covers sexual and asexual reproduction.

According to the phylogenetic definition of species, A, B and C are different species. In the C group, all of them are the same species with different types Picture: Sesbe. Dogs and wolfs are included in the same species, but ethnic groups in fiji are different subspecies Picture: Marc Arenas Camps.

The wings of insects, birds and bats are an homoplasy Picture: Natureduca. There are classfication 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 homoplastic trait is not present bioloogy the common ancestor.

The structures originated by convergence are called analogy. An what is the definition of classification in biology is the wings of insects and birds. Secondary loss or reversion: consist on the iz of a trait to a state that looks ancestral. So, it looks and old state but, in fact, is derived.
