Could someone kindly explain me the difference between Phylogeny, Phylogenetic Tree, Evolutionary Trees, Phylotype, Clusters, OTU (Open Taxonomic Units). Or if possible please do suggest me a beginner's book on that said topics.

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.

  • $\begingroup$ Any evolutionary biology textbook should cover this, e.g. Futuyma's Evolution. To me, your question is too open-ended and broad, and it reads as unresearched homework. $\endgroup$ – fileunderwater Dec 8 '15 at 14:04

Source of information

Understanding Evolution is a free online introductory course of evolutionary biology that will probably answer these questions.

Wikipedia will also make a decent job at answering your questions.

Any introductory book to evolutionary biology would do it.

To answer your question

  • phylogeny = phylogenetic tree = evolutionary tree: evolutionary relationship between lineages
  • phylotype: An observed morphological similarity that is used to classify a group of organisms.
  • OTU: An observed genetic similarity that is used to classify a group of organisms.

Both OTU and phylotype are often used for asexual lineages where the concept of species poorly apply. See more info on the concept of species here.
