Just as strawberries are adapted to birds, so acorns are adapted to squirrels, mangos to bats, and some sedges to ants. That fulfills part of our def… - Jared Diamond

In particular, while natural selection favors both males and females that leave many offspring, the best strategy for doing so may be different for fathers and mothers. That generates a built-in conflict between the parents, a conclusion that all too many humans don’t need scientists to reveal to them. We make jokes about the battle of the sexes, but the battle is neither a joke nor an aberrant accident of how individual fathers or mothers behave on particular occasions. It is indeed perfectly true that behavior that is in a male’s genetic interests may not necessarily be in the interests of his female co-parent, and vice versa. That cruel fact is one of the fundamental causes of human misery.

What are the choices that we must make if we are now to succeed, and not to fail? [...] Two types of choices seem to me to have been crucial to tipping their outcomes towards success or failure: long-term planning, and willingness to reconsider core values. On reflection, we can also recognize the crucial role of these same two choices for the outcomes of our individual lives. One of those choices has depended on the courage to practice long-term thinking, and to make bold, courageous, anticipatory decisions at a time when problems have become perceptible but before they have reached crisis proportions. [...] The other crucial choice illuminated by the past involves the courage to make painful decisions about values. Which of the values that formerly served a society well can continue to be maintained under new changed circumstances? Which of these treasured values must instead be jettisoned and replaced with different approaches?

Religious values tend to be especially deeply held and hence frequent cause of disastrous behaviour. [...] The modern world provides us with abundant secular examples of admirable values to which we cling under conditions where those values no longer make sense [...] It appears to me that much of the rigid opposition to environmental concerns in the First World nowadays involves values acquired early in life and never again reexamined [...].
