(Not for creationists)

Here's an interesting thing I learnt today about the "Last Universal Common Ancestor"s membrane permeability.

Bacteria membranes are made from fatty acids and phosphate groups, while Archaea membranes are made from isoprenes bonded to phosphate groups. Thsee both are impermeable. This suggests that these features were independently evolved, which most likely means that the LUCA membrane was actually permeable.

It's just moments like this that make me love Biology even more
Meh!
