Deep dives
The Strategies of Reproduction
The episode dives into different reproductive strategies among species, primarily discussing R-strategists and K-strategists. R-strategists are characterized by producing a large number of offspring with little care, while K-strategists usually have fewer, but invest significantly in raising each offspring. For instance, insects like mosquitoes exemplify R-strategists by laying thousands of eggs, relying on sheer numbers to ensure some survive. In contrast, species like blue whales represent K-strategists, having long gestation periods and nurturing their single offspring with high-quality milk.
