The Biology of Extremes: Superlative by Matthew D. LaPlante

Spread the love

Superlative: The Biology of Extremes by Matthew D. LaPlante is not just about extremes, but about all the things in between that make the extremes extreme. LaPlante looks at size, speed, age, intelligence. For all the various subtopics that come up in such an exploration, LaPlante does a great job of bringing in the latest research. Mostly, this is a collection of interesting evolutionary and biological stories that happen to involve tiny things, giant things, old things, fast things, or things that are in some other way — superlative.

Go for a swim with a ghost shark, the slowest-evolving creature known to humankind, which is teaching us new ways to think about immunity. Get to know the axolotl, which has the longest-known genome and may hold the secret to cellular regeneration. Learn about Monorhaphis chuni, the oldest discovered animal, which is providing insights into the connection between our terrestrial and aquatic worlds.

I’m not endorsing every idea or story in this book. One can not write a book about adaptations and have any evolutionary biologist worth their salt not bump on things. But the author does an honest and straightforward job of representing the research, and you’ll learn quite a bit that is new, see new perspectives on things you’ve considered in the past, and you’ll enjoy LaPlante’s writing.

I will probably be recommending this volume as a holiday gift for the Uncle who has everything or the teenager who likes natural history. Teachers of wildlife biology, evolution, or related topics will be able to mine this volume for stories. The use of footnotes is notable.* I recommend Superlative

To find out more about the rat in the can effect, you can read this book: The Tangled Wing: Biological Constraints on the Human Spirit by Mel Konner, where I think it is described. Here, I will summarize it, in simplified form. If you seriously need to know about this in more detail, do more research and don’t rely entirely on what I say here.

This is a reposting of an item I originally published in Seed Magazine. The online version of that was lost when Seed went belly-up. I post it here because I occasionally try to refer to it but can never find it. But now, I can!

A Tutorial in Human Behavioral Biology

If you read only one book this holiday season, make it all of the following twenty or so!

But seriously … I’d like to do something today that I’ve been meaning to do, quite literally, for years. I want to run down a selection of readings that would provide any inquisitive person with a solid grounding in Behavioral Biological theory. At the very outset you need to know that this is not about Evolutionary Psychology. Evolutionary Psychology is something different. I’ll explain some other time what the differences are. For now, we are only speaking of fairly traditional Darwinian behavioral theory as applied generally with a focus on sexually reproducing organisms, especially mammals, emphasis on humans and other primates but with lots of birds because they turn out to be important.
