Life must have begin as a cell in water. But then, one quality of this cell was, it can continuously improve.
From one cell it become two. It divided itself in two parts. One part was concerned with reproduction of new cells and with protection of young cells. It was called the Female. Another part of this cell become Male. It's primary function was to fight with adverse circumstances of nature and to develop survival skills for its family.
Then the story went further. Each cell has capacity to reproduce it's better version.
If this theory is correct, then the new generation is always a better version of the old generation.
But the difference is in experience. The old generation is always better experienced than new generation.
Somewhere, the two generations collaborate. And then the mankind goes forward. This is the story of evolution.
