Detecting design or intent in nature

[Heywood]

All those things you describe are small changes. Here is another small change...this time though, it is in a human.

What part of accumulated changes did you miss? You cannot accumulate a smaller rear (1953 to 1955) and drop it off like it never happened (1956) in one generation. Plus, evolution doesn't give you 5 different changes at once (1961). Removing (1962) or adding (1967) a developed heritable trait in one generation isn't allowed by evolution. Your horn examples is not a heritable trait.

The horn example is an example of a small change. You see a woman that grew a horn on side of her head and is in the process of growing a horn on the other side of her head. You might think that is a radical change, but it isn't. The woman is still a human being. The change had no significant impact on what she is. There Ferarri doesn't stop being a Ferrari because in one year it has a smaller rear end.

The human species started out colored brown. Then white skin emerged. But White skin will go away. Some changes come and go but others accumulate.

In the case of the Ferarri, changes which didn't last were eliminated because the engineers felt they decreased fitness. The changes were selected against.
