Humanoids in Science Fiction

Humanoids, often portrayed as extraterrestrial beings with human-like body structures, are integral to science fiction. These humanoid aliens typically exhibit traits such as bipedalism and intelligence, making them relatable yet intriguingly otherworldly. Authors frequently use humanoid characters because they are familiar with only one example of intelligent life: humans.

The prevalence of humanoid aliens in science fiction is partly due to practical reasons. Human actors can easily portray these characters, making them a convenient choice for live-action television and films. For instance, in the series Star Trek, the humanoid appearance of various alien races is explained through the concept of genetic seeding by an ancient civilization.

Theories such as convergent evolution also play a role in these depictions. This theory suggests that different species might independently evolve similar traits, such as bipedalism and intelligence, leading to a humanoid form. Such portrayals not only make for compelling storytelling but also spark curiosity about the possibilities of life beyond Earth.

Humanoids in Mythology and Folklore

In mythology and folklore, humanoids often appear as entities with human traits but possess supernatural powers or features. These entities span various cultures and histories, each with its own unique lore and significance. For instance, mermaids and mermen, with their human upper bodies and fish-like lower bodies, are prevalent in European folklore.
