Embryonic stems cells were only first discovered in 1998 — less than 20 years ago. The video explains what stem cells are (both pluripotent and totipotent), how they become specific types of tissues cells via internal cues such as the cells location in the blastula or transcription factors, or external cues such as the SrY gene in embryos or a change in temperature.
