First-ever demonstration of artificial embryo twinning (jan 2, 1885 – dec 31, 1885)
Description:
Dreisch showed that by shaking two-celled sea urchin embryos, it was possible to separate the cells. Once separated, each cell grew into a complete sea urchin. This showed that each cell has its own complete set of genetic instructions and can grow into a full organism.Added to timeline:
