Detecting design or intent in nature

[Surgenator]

Evolution requires the replication of replicators. Your example fails.

This is just plain wrong. How the population is replicated is inconsequential. Instead of mothers pushing out babies, they could be made in a factory and the stork could be delivering them. All that matters is the future babies be near copies of past babies and any changes which lower fitness are selected against. For instance, Only babies which survive to the age of reproduction will be copied.

You simply fail to understand how evolution works.

Evolution requires accumilated small changes to build and cannot jump between phenotypes. So if we look at your automobile, say the ford mustang. It starts of like

Goes to this

Then jumps in one generation into something less recognizable

Finally it jumps back to something that looks more like it's ancestor in the next generation.

This is not how evolution works, and this one of many reasons your automobile example fails.
