I have read and it has been suggested that some people who have recieved organ transplants have aquired personality traits of their donors.
As a heart transplant recipient I must say I have experienced no such phenomenon myself. However I reserve judgement until I am satified personally that the existing informationm on the subject confirms or refutes claims that cellular memory exists.
I invite anybody who has direct or indirect knowledge of a donor organ that was transplanted and changed the personality of the recipient.

Me and a colleague were discussing, I seemed to remember there was some theory that humans lived semi-aquatically for a while we left the oceans way back in our evolutionary history, my colleague hadn't heard anything about that - any theories?!

Interestingly mammals have very rarely evolved poisonous tissue/blood to counter predation, whereas it is very common in insects and plants and exists to some degree in fish. Is there something that is preventing this from evolving or is it present to a lesser degree in mammals, as in some mammals taste bad etc. I feel there must be an evolutionary trade off to being a poisonous mammal for this not to have occurred, or that to distribute enough quick acting poison is probably impossible in large mammals. But even bad tasting or inedible flesh should be enough for predators to quickly learn not to prey on certain mammals. For instance if rabbits were as poisonous as a cane toad or at least inedible, what would stop rabbits from taking over the world (so to speak)?
That seems to point to me an important fact, that intraspecies competition is driving evolution more strongly than interspecies competition, also possibly digestive counter measures are evolving among predators in tandem

Of course this is not the only unscientific part of this rubbish theory.
How can we expect one explain an eye if he fails to explain a single cell ?
They make ridiculous explanations about how a single cell(which is more complex than a city ) formed .
They have to remember the fact that a complex structure can not live and then diffuse soon , only if one of the components is missing.
How come a single cell will wait "millions of years" and by the help of coincidences , it will complete itself and begin to work.
***
It is the same to believe the idea;
"A timber became furniture after millions of years"
May God give some brain in your heads.
