Merger proposal[edit]

The article on the multicellular organisms consists mainly of two sections on "Evolutionary history" and "Hypotheses for origin". Both of them are treated with more detail in evolution of multicellularity. In turn, the latter article would benefit from an overview of just how often multicellularity actually evolved.

All plants are multicellular?[edit]

This article says all plants are multicellular, but Valonia ventricosa says it is plant and unicellular.--MathFacts (talk) 13:54, 30 September 2010 (UTC)

Simple fix, the article already said 'except for specialized organisms such as'. I've just added the single celled plant there as another exception to the rule Jebus989 13:59, 30 September 2010 (UTC)
The larger issue is that there are multiple definitions of "plant". In the strictest sense they are land plants (all multicellular), whereas algae like Valonia ventricosa are included in the loser definition. So I've excluded algae in the main article. MichaK (talk) 14:56, 30 September 2010 (UTC)

Disadvantages of Multicellularity[edit]

Someone added a section "Disadvantages of Multicellularity" to the article, listing: "Cancer and autoimmune disease. Greater nutritional requirements." I've reverted this, as cancer and autoimmune disease are specific to animal only, but not the numerous other instances of multicellular organisms. The nutritional requirements need to be compared to unicellular organisms. MichaK (talk) 19:00, 10 June 2012 (UTC)

Hi, plants might be able to get cancer, it's just rarer: http://onlinelibrary.wiley.com/doi/10.1111/j.1399-3054.1991.tb02489.x/abstract due to their cells' totipotency. Autoimmune disease is of course limited to multicellular organisms that have immune systems. I think it's important to have a disadvantages section though, even if not the ones listed before.

Evolution of Multicellularity[edit]

The claim that sexual reproduction is a requirement for multicellularity has been flagged "citation needed" for four years, appears to be a non sequitur, and conflicts with other information in the article--e.g. sponges and slime molds which are listed as multicellular can reproduce asexually. — Preceding unsigned comment added by MarkusQ (talkcontribs) 16:55, 9 May 2014 (UTC)
