Why Aliens in Star Trek are So Similar to Humans: An Analysis of Budgetary and Biological Factors

In the vast and diverse universe of Star Trek, the similarity between alien species and humans is a recurrent theme. Why do the aliens in Star Trek mostly differ from humans only in skin color or some peculiar bumps on their heads?

Explaining the Diversity with Budgetary Constraints

While this similarity may seem arbitrary at first glance, it's a creative choice that also accounts for budgetary limitations. As Star Trek's on-screen beings are predominantly humanoid, this design choice simplifies the process of creating different species for the television budget. The use of makeup and prosthetics helps to transform actors into various alien species, making the shows visually engaging and cost-effective.

Convergent Evolution: A Biological Perspective

Biological evolutionists offer a different perspective, explaining the humanoid design through the concept of convergent evolution. This phenomenon occurs when different species evolve similar traits independently, which could be due to similar environmental pressures or similar traits being advantageous. In the context of Star Trek, such traits might include bipedalism, a complex nervous system, and a similar need for technological advancement, leading to humanoid appearances across different civilizations.

Addressing the Fermi Paradox

The similarity in appearance among the aliens in Star Trek actually presents a unique link to the Fermi Paradox, a question in the field of astrophysics and astrobiology which asks, 'if extraterrestrial civilizations are common in our Galaxy, why is there no evidence of their existence?' By presenting a vast number of humanoid species, Star Trek suggests a potential solution to the paradox, hypothesizing that all these aliens share a similar biological or genetic heritage, known as the 'Progenitors.'

Relatability and Practicality

The humanoid design of the aliens in Star Trek serves a practical purpose as well. From the perspective of scriptwriting and acting, humanoid characters provide relatability and allow for a wide range of dramatic performances. Humanoid aliens can be evocative, empathetic, or antagonistic, making them easier to portray and interpret convincingly on screen. This also allows for the extensive use of the same actors in multiple roles, reducing costs further.

Impact on Narrative and Fan Engagement

The relatable and versatile nature of humanoid beings significantly impacts the narrative and fan engagement of Star Trek. It allows for a more profound exploration of human emotions, ideals, and values through diverse alien characters. These characters can represent different moral and cultural perspectives, enriching the storytelling experience. Furthermore, the use of the same actors in multiple roles creates a sense of familiarity and continuity, enhancing the viewing experience for fans.

Gene Roddenberry's Vision

Gene Roddenberry's Star Trek was not only about humanity but also about a broader, interconnected universe. He recognized that humanity's spread could involve a wide range of intelligent species, including those with notable differences, and still be considered distinctly human. This vision suggests a shared heritage or biological background that brings together a diverse array of intelligent life forms in the universe.

Conclusively, the similarity of aliens to humans in Star Trek is a multifaceted decision. It is a creative choice that balances budgetary considerations, biological plausibility, and narrative relatability, contributing to the rich and engaging universe of the series.
