Here's another source
quote: They don't give the Hom... names, but they do show some of the detail in the palaeos.com dendrogram, and it looks like I need to adjust my insertion slightly:

With this nomenclature we have a Hom... designation for each of the major common ancestors in the bush path to human, and I believe that was the intent when these labels were (fairly recently) developed.
Now I may be wrong, but that arrangement makes sense to me. They are, after all, just labels arbitrarily assigned for clarity of discussion. Hominoidae seems to be missing from all the wiki articles, so the taxonomists may have decided to simplify the names ... I don't know. abe The more I look the confusider I gets ... here's more
quote: That would confirm the Hominini classification similar to the Handprint image, but not much else. While I still have some trouble with using the graphic symbols, using this says to me that Darwinius and Haplorhini have a common ancestor and that common ancestor has a common ancestor with Adapiformes└─┬─Adapiformes X While this would imply all three share a single common ancestor├─Adapiformes X and that would be misleading. abe2

RAZD, great job on the tree. I am impressed by your coding ability!
I just wanted to clarify something... I think you understand it, but how you phrased it made me feel it necessary to clarify.
With this nomenclature we have a Hom... designation for each of the major common ancestors in the bush path to human, and I believe that was the intent when these labels were (fairly recently) developed. Hominoidea - where the Hom lineage separates from (excludes) the baboons (Cercopithecidae)Hominoidae - where the Hom lineage separates from (excludes) the gibbons (Hylobatidae) Hominidae - where the Hom lineage separates from (excludes) the orangutans (Ponginae) Homininae - where the Hom lineage separates from (excludes) the gorillas (Gorillinae) Hominini - where the Hom lineage separates from (excludes) the chimpanzees (Panni) Now I may be wrong, but that arrangement makes sense to me. They are, after all, just labels arbitrarily assigned for clarity of discussion. Those names indicate taxonomic rank, not ancestral identification. names ending in "-oidae" are superfamily (or epifamily)names ending in "-idae" are family ending in "-inae" are subfamily ending in "-ini" are tribe So essentially they are the names of the clades and everything after the name are a part of that clade and "Homin" is the base word.
Taxonomic rank endings The terms ‘hominid’ and ‘hominin’ are frequently used in human evolution. New definitions The most commonly used recent definitions are: Hominid — the group consisting of all modern and extinct Great Apes (that is, modern humans, chimpanzees, gorillas and orang-utans plus all their immediate ancestors). Hominin — the group consisting of modern humans, extinct human species and all our immediate ancestors (including members of the genera Homo, Australopithecus, Paranthropus and Ardipithecus). I believe that Hominid is not an official taxonomic rank, but represents a clade that includes those groups listed. Hominin, however, is an official taxonomic rank
While this would imply all three share a single common ancestor
and that would be misleading. No, not misleading. This would indicate an unresolved polytomy which simply means that it is uncertain which branching order would be the best hypothesis. It's possible that all three share a single common ancestor, but it is more likely that we just don't have enough information to resolve the relationships. What's "misleading" or confusing is that the branch tips you show in this example include different ranks. Adapiformes is an infraorder, Darwinius is a genus, and Haporhini is a suborder, so these should not resolve in a trichotomy. But I suspect you only used the names as examples maybe? ------- The thing I find confusing about how your cladogram is depicted, is that taxonomic ranks look like they are at terminals rather than on branches. I see you tried to duplicate the dendrogram in your source, but there is some odd things happening and I don't think it is very clear. It a difficult tree to interpret. For example, I think Adapiformes should be a rank under Strepsirrhini with Darwinius under Adapiformes and Haporhini should be under Primates. Getting the taxonomic names to look more like they are on the branches and not the terminals would go a long way to being better able to see the relationships and solve some of the problems like this. But again, good job on the tree, I just think it is really hard to see the relationships. HBD Edited by herebedragons, : clarityWhoever calls me ignorant shares my own opinion. Sorrowfully and tacitly I recognize my ignorance, when I consider how much I lack of what my mind in its craving for knowledge is sighing for... I console myself with the consideration that this belongs to our common nature. - Francesco Petrarca "Nothing is easier than to persuade people who want to be persuaded and already believe." - another Petrarca gem.

Thanks herebedragons, that was helpful.
Those names indicate taxonomic rank, not ancestral identification. names ending in "-oidae" are superfamily (or epifamily)names ending in "-idae" are family ending in "-inae" are subfamily ending in "-ini" are tribe So essentially they are the names of the clades and everything after the name are a part of that clade and "Homin" is the base word. Where I get confused is Hominoidea andHominoidae Is there another taxonomic rank here? above superfamily? I did email Bruce MacEvoy at handprint.com and he replied
quote: The first link yields
quote: Which introduces Hominina to divide homo from pan (panina?) - which is also mentioned in the New World Encyclopedia article - but otherwise appears to match wiki etc. and it seems to say what you said
For example, I think Adapiformes should be a rank under Strepsirrhini with Darwinius under Adapiformes and Haporhini should be under Primates. ... quote: Are you saying the top should be Archonta The other link also says
quote: Which leads us to personal preferences in the continuing debate of classifications. So at this point I have -- from Haplorhini down: └─Haplorhini Which should resolve the wiki etc issues Enjoy Edited by RAZD, : . Edited by RAZD, : .. Edited by RAZD, : ...

The confusion of the various ranks named after Homo comes from changes in definition.
Once upon a time, 'Hominidae' meant only humans and extinct relatives. The other great apes were classified in 'Pongidae'. The two collectively formed the superfamily Hominoidea. Then, along came the first molecular studies, which indicated that African apes were more closely related to humans than to orangutans. As it became more and more common to consider paraphyletic taxa invalid, taxonomists started to point out that Pongidae was not valid, at least not if it included gorillas and chimps. The change was slow, particularly because palaeoanthropologists had been so long accustomed to use 'hominid' to mean anything closer to us than apes. But to be monophyletic, either chimps and gorillas had to be moved into Hominidae, or a new 'Gorillidae' would need to be invented. The realisation from DNA studies that chimps were closer to us than they were to gorillas would have necessitated an additional Panidae, so the solution that eventually prevailed, and has by now been accepted pretty much universally, is to abolish Pongidae and subsume all great apes under Hominidae. Use of the narrower terms 'Homininae', 'Hominini' and 'Hominina' is not always consistent though, leading to confusion. As the for the question of the difference between Hominoidea and Hominoidae - the latter is a typo.

Handprint.com (Bruce MacEvoy) is staying with his reference ("The Tree of Life" by Lecointre and Le Guyader, 2007) so I'm going to the library tomorrow. I also heard from Palaeos.com on facebook (Renato Filipe Vidal Santos):

Where I get confused is Hominoidea andHominoidae Is there another taxonomic rank here? above superfamily? Sorry, I made a typo there. -oidea is the correct spelling for superfamily -oidae is used for epifamily (although I 'm not sure how often this is used. It seems as if in cladistics, they want a name for just about every clade, so that often requires additional ranks than what we are traditionally used to. )
Are you saying the top should be Archonta First, I want to say that I am not any kind of authority on Primate evolution. Where my "expertise" lies is in phylogenetics and in reading/developing trees (I put expertise in quotes because I don't really consider myself an expert, I am still learning... maybe a better word would be "skill" but even that might be exaggeration ) I like to use the Tree of Life Project (ToL) as a pretty good source for the latest taxonomic classifications. They may not include the most recent updates or the more controversial rearrangements, but they are pretty close. Taxonomy is very contentious (and the human tree even more so) and taxonomists argue and argue about their particular view until a general consensus is reached and then most researchers will adopt the consensus view, but it can take a while til the literature reflects the newest changes. With the advent of molecular methodology and now with deep sequencing techniques, the taxonomic world has gone crazy and there are many competing views on particular groups. But yes, I see that as an accurate depiction of that section. Here's why... This depiction shows Strepsirhini and Haplorhini as sister taxa, not descendants of one another. The lemurs and Adapiformes are descendants or branches within the Strepsirhini, not associated with Haplorhini. I am not sure about the arrangement you have under Strepsirhini, but it is close enough for this project, since it is not really the focus. This is in accordance with ToL - Primates. Haplorhini is not listed on the ToL page, but it is the group that includes Tarsiers, apes and new world monkeys. The branch leading to Platyhini and Catarrhini is the Simians or Simiiformes. On your chart it is listed as Anthropoidea. These names are controversial as to which has precedence. The root Simi is the oldest but the rank name Anthropoidea is older than the name Simiiformes (by 2 years). However, Simiiformes uses the proper rank suffix "-formes" while "-oidea" is supposed to be used for superfamily. So... I personally would favor Simiiformes as the proper name for the rank. You can see the kind of controversies that taxonomists argue about - name precedence and conformation to naming conventions is always a hot issue. I have more comments further down the tree, but I will have to come back to it later. Maybe we could move this discussion to a new thread? Idk, there doesn't seem to be much going on here right now, but I wouldn't want to clog up Porkin's thread with knowledge , but that's up to you. I think this could be a really great tree (actually it already is, it just needs some clarifications). HBDWhoever calls me ignorant shares my own opinion. Sorrowfully and tacitly I recognize my ignorance, when I consider how much I lack of what my mind in its craving for knowledge is sighing for... I console myself with the consideration that this belongs to our common nature. - Francesco Petrarca "Nothing is easier than to persuade people who want to be persuaded and already believe." - another Petrarca gem.

And I had noticed that wiki used Simiiformes instead of Anthropoidea and google has no list for Hominoidae ... so no epifamily in use apparently. Okay, so now we have: Archonta I've requested the book through my local library, they will check the public libraries first and then the RI universities (URI, Brown, Roger Williams).

With the advent of molecular methodology and now with deep sequencing techniques, the taxonomic world has gone crazy and there are many competing views on particular groups. I don't think ToL is a good source for the latest classifications. I can't comment on most of the tree; but vertebrate phylogeny is a bit of a hobby; and here at least ToL seemed to stop updating well over a decade ago. Their vertebrate trees represent what was the conservative view in the 1990s. In 2017 that means they're flat out wrong. While there are lots of issues that are still controversial (where do turtles go, for example); there are many things long universally accepted that ToL contradicts, and I very much wish someone was still updating it, because at the moment it's just misleading.
Open Tree of Life is much more up-to-date; but the problem with this is that it does incorporate a lot of still controversial ideas, and unlike ToLWeb it doesn't tell you when this is the case, nor present alternative hypotheses.

The completist in me is concerned that your tree gives the impression baboons are the only Old World monkey. I tried to edit it but for some reason cannot get the branches to line up properly.
Still, if people thought palaeos diagrams are hard to read - see what happens when I draw it!
