Talk:Maximum parsimony (phylogenetics)

message: Good article, anon, but I wish to improve it to clarify some points and possibly make it more accessible.
OLD:
Maximum parsimony
Maximum parsimony is a simple but popular technique in bioinformatics to predict the 
best phylogenetic tree for an organism.
NEW:
Introduction
Maximum parsimony is a simple but popular technique used in cladistics to predict an 
accurate phylogenetic tree for a set of taxa (commonly a set of species or reproductively-isolated populations of a single species.
Comments: The level 2 heading 'maximum parsimony' is redundant - have replaced with 'Introduction'. 'Bioinformatics' has been replaced with 'cladistics' because the former is more of a broad approach to biological research than a specific field of research. Have removed 'best' from introduction as this does not scientifically-describe the criteria for an optimal tree - 'accurate' is better. In addition, 'best' could be inferred as stating that MP is the best method to produce a tree when there is no consensus that any method is the best under all circumstances. Have also replaced 'organism' with 'set of taxa' and given two examples of appropriate sets to compare.

message: I've done the best I can with what is here, but it would be great if, in the future, someone could break this out into separate artciles for different classes of data, types of analysis, and optimality criteria. As it is, the MP entry is pretty much holding down the entire subject of character-based phylogenetics, which isn't ideal. And, of course, citations would really help alot. Everything in the article is supported, honest. Google Hillis. 24.174.131.158 02:26, 1 January 2007 (UTC)
thread_title:  NEW VERSION 

message: The WP:LEDE is probably too long... and many other nitpicks to be repaired... I'll try to add some cites as time permits but will be busy this week... --Ling.Nut 06:32, 26 August 2007 (UTC)
replies: text: *Mmmm, also looks to me like there may be more than a little shtuff that needs to be moved to some other article(s), such as the paragraph beginning: "Neighbor-joining is a form of star decomposition..." Will do as time permits. --Ling.Nut 07:31, 26 August 2007 (UTC)
replies: text: *Yeah, almost the entire Alternatives section is not directly related to this article & should be moved out to other articles... --Ling.Nut 08:18, 26 August 2007 (UTC)

text: * Plus the Criticism section is looking disturbingly like WP:OR. It was filled with... really blatant violations of WP:SELF as well.. "It has been asserted in a previous version of this article.." Yikes! --Ling.Nut 08:11, 26 August 2007 (UTC)
thread_title:  redo 

message: Great job editing this page!
- Agree on the "alternatives" material: I do hope some of it can be salvaged...
- The "criticism" is not Original Research... most of these criticism IS in fact published, but finding references is not going to be pleasant. Some of the RESPONSES may be even more difficult to find references for.
- I haven't read the "self-referencing" guidlines, but I never actually CITED myself. For what it is worth.
Again, you are doing a great job!  —Preceding unsigned comment added by 128.83.166.125 (talk) 16:04, 7 September 2007 (UTC)
thread_title:  feedback 

message: I have a hard time understanding the example in this section.  In the first paragraph, it is referred to "charactes (A & C)", but surely these are taxa?
Then, is the figure supposed to represent the actual relationship, or the calculated (MP) tree?
While I see the point with only one character, won't the many substitutions (another word could profitably be used here, this seems to assume we're working on a molecular level) between branches A and D ensure that the tree will be more accurate when more characters are taken into account?

thread_title:  clarify "Problems with maximum parsimony pylogeny estimation" 

message: Several times throughout the article, it is said that it's not good to exclude input data only because they have gaps/wildcards. Probably a valid point, but there's no need to hammer. (I also wonder how biologists can use such ad-hoc elimination methods on their data in seemingly arbitrary fashion, without a mathematical proof that they are useful, but maybe I'm misinterpreting the text.)--87.162.58.83 (talk) 04:38, 12 January 2009 (UTC)

thread_title:  Citation Needed 

message: Minimum evolution redirects here, but I don't think it should. MP and ME are different approaches, and there is no mention of ME in this article. In the absence of a separate article on 'minimum evolution', how about having a min evolution section in 'computational phylogenetics', and redirecting there?

thread_title:  Minimum Evolution 

message: I didn't think the lead was serving the needs of an intelligent middle-schooler at all well, so I made rather aggressive structural changes to the lead, while denting the actual text as little as possible—though I did add my own explanatory text concerning the core challenge of phylogenetics to help set the stage.  Having not massaged the original text, the revised structure is not as smooth as it might be (and there are some obvious warts).  I encourage anyone with a sense of appropriate language in this subject domain to further polish the flow.  — MaxEnt 10:51, 12 January 2015 (UTC)
thread_title:  A stab at a simplified lead 

message: I took a second stab to make the lead more comprehensive and less essayish in tone, bumping the last two paras off the lead into a new section titled "Alternate characterization and rationale" (admittedly an ugly limbo) and replacing these two paragraphs with substantive concerns lifted from the main article and mildly restructured for reading level.  — MaxEnt 11:23, 12 January 2015 (UTC)
