Back in 2002, my English teacher in high school handed us a 1- or 2-page short story (definitely not current at the time) and I can't remember the title/author.
The story is about humans crash landing on either Mercury or Venus and quickly evolving/adapting to the shorter days/months/years and living by seconds/minutes/hours.
The story begins with the thoughts of a fetus in the womb, and within moments the being is born and speaking and walking and learning. The "ancients" (or something similar) are teachers and seem to have lived the longest (a couple weeks or so) and describe how it's one's mission in life to cross the ever-changing terrain of the planet. From deathly frozen grounds, quickly thawing and becoming lush land, and again, hust as quickly, turning into fire scorned ground.
The story ends with the protagonist making the trek across the lands to what ends up being a spaceship that had originally crash landed on the planet.
I'm looking for the first (or any) publication of this, as I'd like to find and own a copy.
