• Human embryos have a developmental stage during which they have a tail and

pharyngeal pouches (those pouches develop into gills in fish). How can we explain characteristics of human embryos?

• Human embryos need a tail and gills to breathe during development in the placenta
• Human embryos spend time in the water where tails and gills are useful
