Was There Once an RNA World of Life?

[David N Kempster]

>The seminal work of C. Don Cone during the 1960s and 1970s in fact has
>demonstrated how considerations of membrane voltage and ionic composition
>are critical to understanding mitosis, and that in fact you can make adult
>neural cells divide by manipulating the ionic environment to induce cell
>depolarization (and also block cell division using a similar technique).

>It seems to me that biology has become overly infatuated by the recent
>discovery of genetics, trying to explain everything from the origin of life
>to cancer in these terms.  I would appreciate any comments as to what
>current knowledge indicates as to whether the "bubble on the beach"
>hypothesis for the origin of life may have been possible.  --David Scheim.
