Intelligent Healing System in Mouse Embryo
Humans and most animals have a built-in repair system. Recent research published in the journal Cell examined the protein Lin28a found in mouse (and other) embryos. It causes wounds to grow faster, for instance.
The protein is seldom present in adults (or old animals). However, researchers have engineered mice to produce the protein in adulthood, with positive results.
This is yet another case of researchers copying and using systems that have originally been designed very intelligently.
There's no room for blind Darwinian processes in this scenario.
