Earlier studies suggested that the number of sperm might be just as important as sperm length, if not even more so. With this said, we now have competing information on sperm size, number and the size of the animal making a deposit. So why do mice have longer sperm cells?
Since both mice and elephants and whales often take on multiple mates, it seems that evolution should have made a sperm cell that could discriminate against competitors and kill them along the way to the egg. After all, Mr. Evolution did create eyes, teeth, poisons, claws, brains and other unusual and highly improbable neat ideas along the path of history! Didn’t it?
I don’t know why this article appeared in Science Daily or why anyone would bother to publish these facts with such a poor story to tell for evolution. It seems useless and is not productive to society of humanity or even the mouse. But academics do this kind of stuff. They search through dinosaur poop and daydream of the dangers of dinosaur farts. They measure fruit fly sperm cells and gather whale dung. They seek for answers to life in the remains of the dead and they make up stories to fit their fancy as though this had any value to world peace or human health.
Well did the wise man say:
1 The words of the Teacher,[a] son of David, king in Jerusalem:
2 “Meaningless! Meaningless!”
says the Teacher.
Everything is meaningless.”
3 What do people gain from all their labors
at which they toil under the sun?
4 Generations come and generations go,
but the earth remains forever.
5 The sun rises and the sun sets,
and hurries back to where it rises.
6 The wind blows to the south
and turns to the north;
round and round it goes,
ever returning on its course.
7 All streams flow into the sea,
yet the sea is never full.
To the place the streams come from,
there they return again.
8 All things are wearisome,
more than one can say.
The eye never has enough of seeing,
nor the ear its fill of hearing.
9 What has been will be again,
what has been done will be done again;
there is nothing new under the sun.
10 Is there anything of which one can say,
“Look! This is something new”?
It was here already, long ago;
it was here before our time.
11 No one remembers the former generations,
and even those yet to come
will not be remembered
by those who follow them.
