...chers. Stem cells are undifferentiated cells whose daughters give rise to the specialized cell types that make up an organism. Embryonic stem cells, which emerge in the first days of an embryo's development, have the potential to differentiate, or specialize, into each of the 200 types of tissue in the body.

By calculating the ratio of old-to-young individuals in the samples from each time period, the researchers found a trend of increased survivorship of older adults throughout human evolution.
