Mars Birth: Can Humans Reproduce on Red Planet?
7 Feb
Summary
- Human reproduction on Mars remains an unanswered scientific question.
- Lower Martian gravity may cause fragile bones and childbirth complications.
- Martians may evolve to be smaller and unable to return to Earth.

Humanity's ambition to colonize Mars faces substantial biological challenges, with reproduction being a primary unknown. Professor Scott Solomon's research suggests that whether humans can successfully reproduce and give birth on Mars is still an open question.
The planet's gravity, about one-third of Earth's, could lead to decreased bone density, increasing childbirth risks for Martian-born women. Evolutionary pressures might also favor smaller body sizes due to resource limitations.
These potential adaptations could make individuals born on Mars unable to return to Earth. Their immune systems, exposed to a limited microbial environment, might be vulnerable to Earth's diverse microorganisms.
Solomon's work, detailed in his book 'Becoming Martian,' also explores the cultural divergence that could occur between Earth and Mars over generations, influenced by communication delays and travel difficulties.
While acknowledging the importance of addressing Earth's problems, Solomon believes humanity can pursue space exploration concurrently, aiming to understand our future beyond Earth.
