Why do a chicken embryo and a cow embryo look very similar even though the adults do not?

They are not related, but still have similar development.

They are distantly related, so their development is similar.

The embryos mutate in utero to form different structures.

The genetic makeup of the two species is similar.

They are distantly related, so their development is similar.

Chicken and cows are distantly related by many thousand years ago. The reason of these morphological and physiological differences that occurs later in the development is because of evolutionary biology. Despite this occurrence, almost every organism starts from a gamete to zygote to embryo and etc later on.
