A book that tries to explain why living things behave in a certain way. As far as I can recall, this is where I heard the usage “Selfish Gene” for the first time. Book explains a lot of things in terms of how actions help genes perpetuate themselves.
A few things I recall
What is in it for worker bees in bee hives to keep toiling even though they don’t reproduce. An interesting explanation using rudimentary math (of all things)!!
There was something about why in certain animals, mothers are known to “eat” their progeny to help raise their daughter’s child.
Two chapter titles
You scratch my back, I’ll ride yours
Nice guys finish first
