Definition of phylogeny
The phylogeny is a field within biology is exclusively dedicated to study and know the origin, where they come from, and the development of the different species that inhabit our planet, which also does the same with the genealogies of living beings. The starting point for the phylogeny of organisms is to establish their matches on issues such as DNA, morphology, embryology, the DNA molecules, among others. Of course if one of them gives a positive result then we can talk about genetic relationship and similar evolutionary. There are agencies that are in close relationship with each other in evolutionary terms because for example they can share an ancestry in common, precisely this issue dealt with the phylogeny and phylogenetic, as also is called. However, to carry out this relational study is that it is uses the array of DNA molecules. From this data phylogenetic trees can be produced. In the work of the naturalist Charles Darwin, the origin of species, which dates back to the mid-nineteenth century, appears for the first time drawn this tree which tells us so much about the evolution of living organisms. Meanwhile, these aforementioned genetic trees constitute the Foundation on which rests the phylogenetic classification, which is a type of scientific classification that considers uniquely evolutionarily close relationships among the species that inhabit our planet. Also reconstructs the history of how they were diversifying, since they first appeared on Earth until present times. In case this information as well as being vital to meet a kind, know why has such or which features, is super enriching because it also allows us to know for certain which species come from others, some untimely disappearance, their mutations, among other issues. Certainly Darwin was a pioneer and who largely owe the desire to discover the evolutionary history of the species. Their proposal called as natural selection was it for the best explaining biological evolution. According to their theories an environmental conditions will be key in favour or hinder the development of a species.
