CHIMERAS: Canalization and epigenetic landscapes: if horses and rhinoceroses share the same ancestor, why don't we have rhinohorses?

The expression "epigenetic landscape" was coined by British developmental biologist Conrad Hal Waddington (1905-1975). He compared gene regulation during development to marbles rolling downhill towards a wall. As cells differentiate, the different cell fates are represented by the lowest points in a landscape made of several pits, some lower than others. Waddington also coined the expression "canalization" to describe the ability of organisms to produce the same phenotype against genetic and environmental variations.

Among the most fundamental challenges facing the scientists will be developing new computer models that more accurately predict the behavior of cells in the laboratory. Scientists can already program individual cells to complete certain tasks but scaling up to create a larger organism is trickier.
