Assuming that Mars held an atmosphere capable of supporting life (and always has), what would a martian bird look like when compared to it's earthen counterpart?
- The gravity difference remains the same between planets.
- The atmosphere is roughly half of what it is on Earth.
- The ecosystem of the planet is similar to earthen deserts and tundras.
- You can pick any bird that you feel would best illustrate the differences.
https://en.m.wikipedia.org/wiki/Bird - This will serve as the definition. If the specifics of evolution/biology cause too many problems, then assume that Mars came to posess creatures that share the many qualities that we associate with birds. Also, an exact scientific answer is hardly necessary, approximations based on our current understanding of these things will suffice.
While this question certainly requires the use of opinion and guestimations to some extent, it is rooted in logical conclusions. In what ways would a Martian bird be different based on the necessary adaptations to the Martian environment. For example...
- Would they be overall larger/smaller.
- Would wings be bigger/smaller.
- Would the tail be longer/shorter.
- Would feathers be longer/shorter.
- Would bones be thicker/thinner.
- Would muscles be more/less developed.
- Would legs be longer/shorter.
- Would beak shape be effected.
- Would eye size be effected.
- Would lung capacity increase/decrease.
These are all very simple ways of describing the appearance of something as it pertains to biological adaptations.
