Scientists recreate mouse from gene older than animal life
>formatting linkNew research sheds light on evolutionary origins of stem cells with groundbreaking experiment to create mouse using ancient genetic tools
It is probably not a coincidence that the single celled creature they used for this was an ancient flagellate. They were the first living things to actually have a viable protein motor of sorts and a whip tail which gave them their name.
Last common ancestor still with genes close enough to work in a mammal.
There may well be fungi or slime moulds similarly capable of this trick.
