Do vertebrate embryos develop the same structures at different rates?

Answer 1

Vertebrate embryos do not develop the same structures at the same rate. Each species has its own unique developmental timeline. Additionally, within a species, different structures may develop at different rates. For example, in humans, the nervous system develops earlier than the digestive system. This variability in developmental rates allows for different structures to form and mature in the appropriate sequence for the specific needs of each organism.
