Discussion Overview

The discussion centers around phylogenetic trees, exploring their role as data and graphical models in evolutionary biology. Participants inquire about applications of these trees, including both pre-existing models and the process of constructing new ones for research or biological explanations.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant notes that phylogenetic trees are used to model evolution and mentions that the distances between species are calculated using float numbers, suggesting that the model is approximate.
  • Another participant shares their experience with a specific software, Mesquite, for working with phylogenetic trees and mentions other tools like MultiDendrograms, TreeDyn, and FastME, indicating a variety of available resources.
  • A participant expresses their interest in the field of phylogenetics, highlighting the aesthetic appeal of the diversity represented in phylogenetic trees.
  • Another participant recommends DNASubway as an introductory tool for constructing phylogenetic relationships, particularly at the molecular level, and points out the availability of a manual for guidance.

Areas of Agreement / Disagreement

Participants express varied experiences and interests in phylogenetic trees, but there is no consensus on specific applications or methodologies. Multiple tools and approaches are mentioned without agreement on a preferred method.

Contextual Notes

Some limitations include the participants' varying levels of familiarity with phylogenetic trees and the tools mentioned, as well as the potential for differing interpretations of the data and models involved.

Who May Find This Useful

This discussion may be useful for individuals interested in evolutionary biology, computational biology, or those seeking tools for constructing or analyzing phylogenetic trees.

I only know that Phylogenetic tree is used as a data and graphical model for evolution. It looks nothing really special. Perhaps because my knowledge about it is still limited. Because distances between species are calculated using float numbers (right ?), the model is considered as approximate. If you have worked with phylogenetic trees, could you introduce applications that need you to use read and use ready made trees (likely data are stored in XML files) and those that you need to build one yourself for research or biological phenomena explanation purposes ? Thank you a lot,

Sorry only have to be brief and answer one of your questions. In the past I've Mesquite. Its rather fun, even if it is just for curiosity's sake.

Other ones I've heard about but haven't used myself are; MultiDendrograms, TreeDyn and FastME.

There is a pretty big list here at bio-soft.
 
Thank you, this phylogenetic science field is difficult to me but I like it. I look at this
http://tolweb.org/Eukaryotes see how beautiful they are (from big animals to tiny insects, and different flowering plants, that is cool)

hey phylotree,

not sure if you're still looking for help with this, but DNASubway (google it, can't post links...) has a great introductory level tool for constructing phylogenetic relationships and learning about phylogenetics in general, on a molecular (dna, protein) level. In particular, you'll want to go on the 'blue line' They have a manual (find the link in the footer of the page) that can help walk you through it.
