By way of experiment...

By way of experiment, it has been possible, for example, in certain mammals (female rabbits), to obtain the beginnings of a development of the ovule into an embryo at an extremely rudimentary stage without any intervention of spermatozoon. It was not possible to go any further however and an example of complete parthenogenesis, whether experimental or natural, is unknown. Jesus is an unique case. Mary was a virgin mother. She preserved her virginity and did not have any children apart from Jesus.

Jesus is a biological exception.[^34] THE GENEALOGIES OF JESUS. The two genealogies contained in Matthew's and Luke's Gospels give rise to problems of verisimilitude, and conformity with scientific data, and hence authenticity. These problems are a source of great embarrassment to Christian commentators because the latter refuse to see in them what is very obviously the product of human imagination.

The authors of the Sacerdotal text of Genesis, Sixth century B.C., had already been inspired by imagination for their genealogies of the first men. It again inspired Matthew and Luke for the data they did not take from the Old Testament. One must straight away note that the male genealogies have absolutely no relevance to Jesus. Were one to give a genealogy to Mary's only son, who was without a biological father, it would have to be the genealogy of his mother Mary.

Here is the text of the Revised Standard Version of the Bible, 1952: The genealogy according to Matthew is at the beginning of his Gospel: So all the generations from Abraham to David were fourteen generations, and from David to the deportation to Babylon fourteen generations, and from the deportation to Babylon to the Christ fourteen generations". (Matthew, I, 1-17) The genealogy given by Luke (3, 23-38) is different from Matthew.
