This is all part of what Liberalism is, biologically, which is the r-selected reproductive strategy in humans.
In evolutionary biology, r/K selection theory basically says organisms tend to adopt one of two psychologies, which guide their behavior. These two psychologies are identical to Conservatism and Liberalism, and indeed, you can look at other more primitive species, and see the more primitive forms of our ideologies in them.
The K-selected psychology is designed for an environment of limited resources, where one must compete to acquire resources, and where those who fail to compete die. One example would be the wolf. This produces individuals who are individually competitive, monogamous, prone to high-investment, two parent parenting, prone to wait until fully mature to mate, and who exhibit loyalty to a competitive in-group. The reason for monogamy with a carefully selected mate, two parent rearing, and offspring waiting until maximally mature before taking a mate, is to maximize the offspring’s fitness, since they need to be able to outcompete peers for food. Mating with just anyone produces less fit offspring, as does inferior rearing strategies, or trying to mate before mature. K-selected males tend to be big, aggressive, and take the role of protecting offspring, while females tend to be feminine, by our K-selected standards, and take the role of nurturing offspring, and guiding them away from danger.
The r-selected psychology is designed for an environment of resource abundance, where one doesn’t need to compete for any of the over-abundant resources, and where competing is actually a needless danger, which Darwin selects against. An example of this is the rabbit, which lies in a field of grass it could never possibly eat. Since there is no competition, every offspring will survive, and there is no reason to focus on carefully producing a few, highly fit offspring. Instead, any offspring, no matter how stupid, can survive.
This produces a population which is averse to competition, and which flees from any danger, and which maximizes offspring numbers through promiscuity, single parenting, and mating as early as possible (without any care for offspring fitness. Since there is no competition, they will also not have any loyalty to in-group (the very notion of in-group would be foreign to them).
r-selected organisms see the females become big and manly, by our K-selected standards, since they raise offspring alone and need to be strong enough to provision and protect them. Ever see some of these man-jawed, muscle-bound, hyper-ambitious feminist chicks? r-selected males tend to be designed solely for fleeing and fornicating, and will become diminutive, cowardly, and focused on superficial flash over competitive substance. Think Gavin Newsom, or any other metrosexual manboob, aka Rush Limbaugh’s Castrati.
Every aspect of Liberalism relates to the r-strategy, as that is what a Liberal is- a human r-strategist. Even the sexual dimorphism matches.
You can’t understand politics, or the bizarre things Liberals do without understanding r/K Selection Theory, and how every aspect of their ideology is an adaptation to the r-selective environment.
Check out my website and my blog, if this interests you (there’s a book for sale on the site, but you’ll have more than enough to read just on the website and blog, and it will explain this plenty well). Later this week, I role out a pretty cool blog post discussing neurological correlates between Homosexuals and Liberals, how homosexuality is probably just an extreme form of the r-selected reproductive strategy, and how studies of the balancing selection hypothesis of Homosexuality supports this perfectly. (In other words, there is scientific evidence which supports the hypothesis that Liberals are just moderated Homosexuals, and homosexuals are just nature periodically overshooting the r-type Liberal mark.) Plus there is other interesting stuff on brain function, psychology, and ideology in the blog.
Also a pretty long, technical look at what ideologies are about, and how they emerge from the brain here in pdf form:

Interesting read, thank you.
