A new "atlas" of early embryonic development in mammals suggests that the process is highly chaotic — but there is some method to the madness. When you purchase through links on our site, we may earn ...

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

Research improves upon a popular experimental model of mammal development and in doing so, reveals more of the inner workings of a critical period during the formation of an embryo. Research from Ph.D ...

Chevrotains are among the smallest hoofed mammals on Earth, standing little more than a foot tall. Despite their size, they share deep evolutionary roots with much larger ungulates. Researchers study ...

Growth of bone, muscle and fat during childhood and adolescence / J.M. Tanner -- Bone growth and remodelling / H.A. Sissons -- Some problems associated with the development of the mammalian skeletal ...

Seals give birth only when conditions are right. After mating, a female seal can delay implantation of the embryo in the uterine wall—pausing pregnancy until she senses that her fat reserves are ...

Biochemical ‘DNA methylation’ marks are found across the genome in vertebrate animals, but in the early embryos of placental mammals, such as mice and humans, they are largely erased in a ‘system ...

What distinguishes the growth and development patterns of early mammals of the Jurassic period? Paleontologists have been able to gauge the lifespan and growth rates of these ancient animals, and even ...
