Do fish and mammal embryo share any features in the late stages of development or in the early stages of development
Fish and mammal embryos share some common features in their early stages of development, including the formation of a notochord and pharyngeal gill slits. However, as development progresses, these features become more distinct between the two groups.
In the late stages of development, fish embryos continue to exhibit characteristics such as a tail fin and gills, while mammal embryos develop structures like limbs and a placenta. Furthermore, fish embryos develop externally in water, while mammal embryos develop internally within the mother's uterus.
Overall, while both fish and mammal embryos share some common developmental features, there are also distinct differences that reflect the unique evolutionary paths and adaptations of each group.
