Dawkins on Pinker:

The Blank Slate is ... a stylish piece of work. I won't say it is better than The Language Instinct or How the Mind Works, but it is as good—which is very high praise indeed. What a superb thinker and writer he is: what a role model to young scientists. And how courageous to buck the liberal trend in science, while remaining in person the best sort of liberal. Pinker is a star, and the world of science is lucky to have him.

Exhibit 1 is surely http://en.wikipedia.org/wiki/E._O._Wilson - father of sociobiology.

It's a good book, but see also Debunking Adapting Minds.

Amazon's summary has:

Buller argues that our minds are not adapted to the Pleistocene, but, like the immune system, are continually adapting, over both evolutionary time and individual lifetimes. We must move beyond the reigning orthodoxy of evolutionary psychology to reach an accurate understanding of how human psychology is influenced by evolution. When we do, Buller claims, we will abandon not only the quest for human nature but the very idea of human nature itself.

IMO, that does an excellent job of making the author sound clueless.

I haven't read Adapting Minds, but I've seen responses to it by evolutionary psychologists. You can find a bunch of them on Cosmides' and Tooby's website

See this one by Delton, Robertson, and Kenrick for instance:

After what might seem like a reasonable review of the mate preferences literature, Buller concludes that evolutionary psychologists are mistaken in their claims of a universal male preference for relatively young women as mates and a universal female preference for high status men as mates. Male mating preferences, Buller argues, although sometimes containing a preference for young women, are far more complicated. We agree with this conclusion, but not because he demolishes the empirical evidence, or because his theoretical acumen is sharper than the many evolutionary psychologists who have written on this issue. Instead, we agree because the “alternative” he proposes is essentially the reigning consensus among evolutionary psychologists. He fails to understand that evolutionary psychologists also believe that people in different situations will behave differently. For instance, college aged fraternity boys and elderly widowers face different circumstances and are at different life-history stages; no one would expect them to have identical mates. Regarding the female preference for high status males, Buller goes even further, arguing that it is in fact non-existent—an artifact of skewed samples and mating preferences for similar others. In this conclusion, he is simply wrong, and we present evidence explaining why below. Indeed, much of the evidence we will cite is in papers he cites during his criticism, except that he repeatedly misconstrues the findings along the way.

...

Buller’s arguments to the contrary have been shown to be false, superfluous, or a slight variant on the consensus of evolutionary psychologists. Throughout this response we have relied mainly on data and theories that were published prior to Buller’s book. Most of this work was available in papers he himself cites or was published by researchers whose work he is criticizing. Theories of shifting strategies have always been part of evolutionary psychologists’ theories. Buller has created a straw man: He implies that evolutionary psychologists have hypothesized that each sex has a single-minded focus on only one characteristic of potential mates—youth or status—regardless of other factors. In reality, evolutionary psychologists have always included multiple preferences in their theories of mate choice (see Buss’ textbook, 2004). He suggests that homogamy is a potent force in mating and that it explains many empirical phenomena for both sexes. This isn’t new or an alternative: Over a decade ago, Kenrick and Keefe (1992) incorporated similarity preferences into their evolutionary model. Buller’s one original hypothesis, the age-adjusted homogamy hypothesis, fails to convincingly account for any previously unexplained data.

Another negative review from Machery and Barrett concluded:

Buller has failed to mount a successful challenge to evolutionary psychology. Most of his critiques of the theoretical commitments of evolutionary psychology miss the mark. Some misrepresent the literature; others are fallacious, drawing untenable conclusions from admittedly uncontroversial premises. His attacks against the empirical findings are similarly erroneous. Most important, if Buller were right, there would remain little place for a science at the intersection of psychology and evolutionary biology. If, as he claims, Buller actually endorses evolutionary approaches to human behavior, but simply wants to raise the standards of the field, his book, alas, fails to do so.

The arguments of Buller's critics seem well-reasoned and well-cited, though someone who has read his book would have to confirm that they are fair to him.

I'm guessing that most laypeople here identify Ev Psych with the sort of explanations offered in Pinker's How the Mind Works and The Blank Slate. Are those the kinds of explanations that you consider to be pseudoscience?

There's chimps and bonobos - and other primates. That is quite a few "data points" - considering the mountain of information that can be obtained from each of them.
