An Overview of Embryonic Stem Cells

... were found able to propagate indefinitely in the undifferentiated state while still conserve the capacity to differentiate to all mature somatic phenotypes. The initial isolation of murine ES cell lines in 1981 contributed to a simple model system for studying the basic processes of early embryonic ...

How Does Natural Selection Create Ordered Variation?

... one. And if factors change most of the time they don't change for all individuals of a species - only for a population. So you get a variety of phenotypes. And if species can't adapt to occuring changes they will eventually die out, but that may take a few couple of hundreds of thousands of ...

Re: Theories - Origin of Life

... mechanisms correct those errors (or cause the resulting piece of DNA to be so broken that it isn't viable) so that by the time you are looking at phenotypes, most mutations are neutral because many of the most harmful ones have been weeded out.
