The possibility exist that information is introduced from an external source which directs the activity. Why can't that be admitted by some supposed scientist?

What would be the motive for such an assumption?

It suggests that further research is unnecessary and futile.

The assumption or invisible entities twiddling with things could have been invoked at any time and any place in science, bringing curiosity and research to a halt.

On the contrary!!! It should suggest even more aggressive research be done, since there is no CLEAR fact as to what directs the action of the cells!

...I'm not sure I follow but let me interject it would be tragic if research came to a halt since we don't have a clear observable answer. All we have now is speculation, conjecture, and theory. I don't have the answer and neither does science yet, but I'm all 100% behind science to research to find these answers.
