CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -The classic example of mate choice is a peacock’s tail. Peahens prefer peacocks with large and colourful tails, so those peacocks get to mate more frequently and have more offspring. The male peachicks will inherit the genes for a long and colourful tail from their father and so will have a similar tail.

Detailed explanation-2: -Darwin’s theory of sexual selection says that nature’s extravagances–like the peacock’s tail–are advantages in the mating game. Marion Petrie, working with peacocks, found that peahens choose their mates by the size and shape of his tail.

Detailed explanation-3: -The degree of sexual dimorphism found in the majority of species of birds-of-paradise (cryptically coloured females while males have spectacular ornamented plumages and elaborate courtship displays) is one of the most prominent avian examples of sexual selection.

Detailed explanation-4: -Evolution by sexual selection has been invoked to explain a number of human anatomical features, which appear useless or detrimental to human survival. These include hairlessness, male facial hair, rounded breasts, pubic hair, and penis size.

Detailed explanation-5: -This type of sexual selection generally involves the evolution of elaborate behavioral displays or physical traits to attract mates. These can be things like a mating dance or call, bright feathers, and large genitalia. Intersexual selection can be observed in many species, including flies, pigeons, mice, and monkeys.
