Migration

He was exchanging letters with the swiss ant expert
about this ant, that is just like the British ant, but not exactly.


What does that mean?
Could the british ant in ancient times somehow have migrated
to England, and later evolved there to become slightly different?


During those times, most mail with Europe was carried by pigeons.


So fascinated was he with exchanging science ideas,
that he started hanging out with the postal servicemen.
The pigeon growers.
He even raised pigeons for six years just to see
if he can produce a pigeon with a red tail.


But the letter from the swiss ant scientist is long overdue.
So he walks over to the local post office and demands:
Where is my pigeon?


Uhm, well, we've been having some problems with that lately.
Along the coast there are hawks waiting for the exausted pigeons.
Your pigeon may have been someone's dinner.


Furiously, he walks over to the beech,
endlessly searching for his pigeon.
With the eyes of the scientist that he is,
he spots their wedding ring in a regurgitated pellet of a hawk.


All that is left of his pigeon are some seeds she picked
up for the trip and never managed to digest.


So he takes the seeds, and lets them germinate,
and he sees the most beautiful flowers -
which he knows well from his back yard.


So that is how they migrated to England!

Replication

A replicator is a creature that can make copies,
or replications of itself.

When a woman bears a child, he is similar in charachter
to his mother and father: he is human.

Humans are replicators.

When a replicator makes a copy of itself,
there are now two of them.

Next time, both will replicated and there will be 4.

Next time, there will be 8.

Next time 16.

At the tenth time, 1024.

At the 20th time, about a million.

At the 30th time, a billion.

If adam and eve bore four children, doubling
their quantity, and so on with each generation,
there would be a billion people on earth
in thirty generations.

The Cockroach female,
in her lifetime, will lay up to a million eggs,
in some cockroach species.

Try to imagine this:

One female cockroach would live and die in about one year,
leaving a million cockroches.

Each of the half a million females will do the same next year,
leaving 500 billion cockroaches around.

Next year there will be more.


In The Origin Of Species,
Charles Darwin gives a long and detailed
account of how quickly different animals in Nature would grow
to cover the earth.
