I read the following question and answer from your web site, and I understand the explaination of recapitulating phylogeny, but is it actually possible for babies to be born with either something resembling "gill slits" or a "tail"? Possibly flaps of skin or an elongated tail bone? Question - Is it true that babies can be born with a congenital throwback i.e. born with fish gill/s and if so what is it called?

All mammals have gill slits in their very early fetal development. We call this ontogeny recapitulating phylogeny..where the development of the individual goes through some of the characteristics of the animals lower in the evolutional development. When we look at early fetal development of various animals we see all having gill slits, and tails.

Yes ... almost anything is possible. Although usually not for the reasons that one might expect. What congenital anomalies of development show are often related to the time of delivery/parturition.
