Is there only one optimal configuration an organism can reach during evolution? Is there a single formula that describes the trajectory towards the optimum? And can we 'derive' it in a purely ...

A new study from the Max Planck Institute for Evolutionary Biology has uncovered how the MN1 gene evolved to shape both the brain and skull during embryogenesis—a link with profound implications for ...

Small fold – big role: A tissue fold known as the cephalic furrow, an evolutionary novelty that forms between the head and the trunk of fly embryos, plays a mechanical role in stabilizing embryonic ...

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, ...

An international team of experts in embryology and bioethics has published the first white paper on the use of embryonic models based on stem cells in the field of reproductive biology. The document, ...

WASHINGTON (Reuters) -Bipedal locomotion - walking upright on two legs - is a fundamental trait underpinning humankind's success. Scientists now have identified two innovations that occurred long ago ...

Feathers are among the most complex cutaneous appendages in the animal kingdom. While their evolutionary origin has been widely debated, paleontological discoveries and developmental biology studies ...

Have you ever looked at a human embryo and thought, “That kind of looks like a fish”? If you haven’t, you might be surprised to learn that, in a way, we all begin our lives like this. The idea that ...

A new study reveals that age-related autophagy decline blocks embryo development by triggering a lipid-burning crisis.
