Maternal secrets of our earliest ancestors unlocked
New research brings to light for the first time the evolution of maternal roles and parenting responsibilities in one of our oldest evolutionary ancestors.

Tooth chemistry analyses enable scientists to 'read' more than two-million-year-old teeth. Finding demonstrates why early human ancestors had fewer offspring and extended parenting role.

Most reptiles and fish have multiple sets of teeth during their lifetime. However, most mammals, such as humans, have only one set of replacement teeth and some mammals, like mice, have only a single set with no replacement. This diversity raises both evolutionary questions -- how did different tooth replacement strategies evolve? -- and developmental ones -- which mechanisms prevent replacement teeth in animals that lost them?
