Humans do not have tails, but do we have “what it takes” for a tail? Hens don’t have teeth, but they have the genes for it. With atavism, it is as if our genomes serve as archives of our evolutionary ...

Scientists captured first real-time 3D video of human embryo implantation, revealing mechanical forces behind successful ...

What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and ...

Seals give birth only when conditions are right. After mating, a female seal can delay implantation of the embryo in the ...

Over the past year or two, we have been exploring what we termed the origins—or the embryology—of human development. We examined the three pillars of development: Feelings (Affects), Language, and ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Nearly half the embryos studied underwent developmental arrest because of genetic mishaps in early development—a revealing insight that suggests more IVF babies could come to term with changes in the ...

Transposable elements are stretches of DNA that can move around the genome. Many of these DNA sequences originate from long ...
