Hayflick never refuted Carrel's chicken heart experiment. He showed that differentiated cells do have a replication limit “the Hayflick limit”. But immortal cell lines can and do get produced from differentiated cells.

HeLa cells are an immortal cell line taken from the cervical cancer of Henrietta Lacks.

Alexis Carrel reportedly kept a chicken heart cell culture going for twenty years. Without an actual sample of the culture it is impossible to conclude if he actually had an immortal cell line.

Either way the conclusions that Carrel drew from it, that all cell lines would be immortal, was obviously in error. Hayflick corrected that error.

Amazing how the power of Science to discover and correct error is attempted to be used to suggest that all Science is in error; and that we need not even consider the implications of data, because later it might be found to have a flaw in one of the conclusions taken from it.

Hayflick never refuted Carrel's chicken heart experiment.

Sure he did. Carrel's experiment with noncancerous cells was used to advance the false theory that cellular aging was solely due to environmental conditions.

HeLa cells are an immortal cell line taken from the cervical cancer of Henrietta Lacks.

And those cells survive due to genetic factors, not environment.

Evne changing the subject, you shoot yourself in the foot.
