Miles from Nowhere (2024)
S01E12 Continuing the Line
Episode Overview
The series finale explores how different species achieve their primary mission of passing on their genetic legacy. This challenge has led to a myriad of unique adaptations. For instance, barnacles, despite their immobility, possess both male and female reproductive cells, making any neighboring barnacle a potential mate. In contrast, a female elephant endures an extensive 22-month gestation, carefully selecting a strong male to father her calf. Meanwhile, a female chinchilla employs a drastic rejection method, squirting urine at unwanted suitors. Mating can be perilous, as seen with a cautious male tarantula that must evade her venomous fangs before proceeding. Timing is crucial for some, like male crabs, who can only mate when a female has recently shed her shell. Male sea lions fiercely compete for a harem, with some resorting to stealing reluctant females. Attenborough notes that human monogamy is quite rare in the animal realm
