Lamarcin teoria todistettu ?
Wikipedia sanoo laakamadoista:
In 1955, Thompson and James V. McConnell conditioned planarian flatworms by pairing a bright light with an electric shock. After repeating this several times they took away the electric shock, and only exposed them to the bright light. The flatworms would react to the bright light as if they had been shocked. Thompson and McConnell found that if they cut the worm in two, and allowed both worms to regenerate each half would develop the light-shock reaction. In 1962, McConnell repeated the experiment, but instead of cutting the trained flatworms in two he ground them into small pieces and fed them to other flatworms. Incredibly these flatworms learned to associate the bright light with a shock much faster than flatworms who had not been fed trained worms.
Onko tätä aihetta käsitelty täällä joskus ? Voisin tietenkin tehdä haun.
Onkohan tätä tehty kylmällä valolla ? Ettei ole kyse infrapunasta, vaan nimen omaan valosta.
