Vertebrate embryos: developed the same structures at different rates? Developed different structures at the same rate? Go through the same developmental stages at the same rate? Or go through the same development stages at a different rate?
Vertebrate embryos generally go through the same developmental stages at different rates. While the same structures are being developed, the timing of their development can vary across different vertebrate species. This phenomenon is known as heterochrony. For example, the development of certain organs or limbs may occur earlier in one species compared to another. Additionally, slight differences in the timing of development can also be observed within the same species due to genetic and environmental factors. So overall, vertebrate embryos go through the same developmental stages but at different rates.
