Disambiguation from Bateman's principle[edit]

Trivers' PI theory here needs to be disambiguated from Bateman's principle Pete.Hurd 01:44, 18 August 2005 (UTC)

Done. Richard001 06:22, 13 July 2007 (UTC)

Summary[edit]

There needs to be a short, more clear and concise summery of this article.

That is, a lead section. Richard001 00:56, 13 July 2007 (UTC)

Human parental investment[edit]

And where's the article for human parents "investing" in their children's education, upbringing, helping them get started in business or society, etc.? I met a socialist politician once who vehemently objected to the idea that "parents who love their children more" could provide any advantages to them! --Uncle Ed 15:48, 25 January 2007 (UTC)

This is about evolutionary biology theory, and is a technical term often used. If you want to create something for humans, start from the parenting article and break it off into a new article if it gets large enough. Richard001 00:56, 13 July 2007 (UTC)

Parental investment as a subject of evolutionary psychology not evolutionary biology[edit]

Hence renamed it and added quite a bit to the article. — Preceding unsigned comment added by Teddykra (talkcontribs) 17:26, 22 December 2011 (UTC)

Why? It is a topic within the study of biology in general, not just within EP. People study parental investment in plants... — Preceding unsigned comment added by 129.128.52.193 (talk) 17:14, 23 December 2011 (UTC)
Agreed. Parental Investment Theory, as proposed by Robert Trivers, is a highly influential principle in evolutionary biology in general, an one of the foundational principles of comparative animal behavior. Memills (talk) 02:38, 24 December 2011 (UTC)

How Evolution Ties In[edit]

The evolutionary changes of parental investment among species need to be discussed. Although the changes of offspring are discussed, as well as sexual selection, a specific evolutionary force, evolution should be mentioned and discussed in detail. Stuhlreyer.7 (talk) 12:50, 1 October 2014 (UTC)

Sexual Selection[edit]

At the end of the article's second paragraph, sexual selection is discussed and explained in detail - mentioning that in humans, there is competition among the males and selection among females because of females higher parental investment and goes on to explain that a female will chose a mate with the highest fitness and good genes- but sexual selection is not mentioned by name.
