Do the gill slits present in the early embryonic stages indicate that humans evolved from a fish-like ancestor?

The so called gill slits do not develop into any part of the respiratory system. The appearance of similarity has no genetic reality.

Hackel's drawings greatly exaggerated the similarities. The actual photographs of embryos do not support Hackel's theory that embryos reflect an evolutionary relationship.

It is sad that some text books still use Hackel's drawings as illustrations, as the drawings do not reflect a scientific reality.
