Vertebrate embryos develop the same structures at different rates. This means that while the basic structures may be similar among different species, the speed at which these structures form and mature varies.
In contrast, some organisms, like cephalopods, develop different structures at the same time. For example, octopuses have well-developed sensory and motor systems in their embryos, which allows them to exhibit complex behaviors even before hatching.
Additionally, vertebrate embryos can go through the same developmental stages at different rates. This means that different species may take varying amounts of time to reach key milestones during embryonic development, such as the formation of limbs or the development of organs.
However, it is also important to note that vertebrate embryos generally go through the same developmental stages at the same rate. There are certain predetermined sequences of events that occur during embryogenesis, such as gastrulation, neurulation, and organogenesis, which are conserved across vertebrate species.
