Pregnancy and multiple births

Duration 03:56

From a single fertilised cell to a fully grown baby, this footage mixes CGI with real-life shots to paint a picture of how we develop inside the womb. The examples focus on real life caesarean multiple births as extreme examples of normal development. Footage includes synchronised divers and a caesarean section. It gives an example of both identical and non-identical multiple births.

Use this clip as part of a lesson in human reproduction, as an example of how a woman's biology sometimes leads to more unusual reproductive outcomes. Identical twins could be used to explore ideas of variation and inheritance. Family photos could be used to compare physical features and demonstrate the difference between twins and other siblings.
