Only the Fittest improve their Fitness

For some of us, life is a game

Yesterday's gone, Tomorrow's the same

For people, we made life rather tame

A life that is tame is not a life that is lame

We've adapted to the world, and now make the world adapt to us

We can change the planet's face, if it gives us a fuss

There'll always be a battle between people and nature

We make tools and environments, constructing our fate, sure

Other animals don't have our own gifts

This homes, their environments, they must be perfect fits

When it comes to biology

There's reproductive strategy

R or K selected,

Propagation, how do they perfect it?

In the survival of their progeny, how much are they protected?

How much time and energy will these parents have invested?

Yet, even if it seems that they don't care about their youth

I must tell You, this is not the fundamental truth

Animals of varying species care about their offspring

Giving the best chance for their species is the parent's only offering

Some babes are fully formed, already running on instinct

Other's must stay by the parents' side, having to learn behaviors that are distinct

Some parents can't help their babes, since the parents still need to survive

Other species die for their kids, self-sacrificing their own lives

Some provide their babes with their own first meals

Milk, blood, prey, hay, even their own flesh, that's the deal

Some animals can only hope if given the circumstances

That if they produce enough offspring, some'll survive given the "Chances."
