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 ...

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, ...

Embryo organoids made from stem cells are enabling scientists to recreate early pregnancy in the lab, unlocking treatments ...

Chimpanzee naive pluripotent stem cells (PSCs) can now be grown in cellular cultures, reveals a recent study. They successfully created chimpanzee early embryo models, called 'blastoids,' and found ...

A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

Learn how birds and mammals share the same genetic toolkit that helps them develop their faces, and why they don't look the ...

The Gazette offers audio versions of articles using Instaread. Some words may be mispronounced. Every time I see a letter denouncing evolution, I think back to my sixth-grade science class where the ...
