Yolks are an important component of the eggs since they
nourish the young embryo as it develops into a young juvenile organism. The
yolk is important especially when the embryo is not attached to its parent (in
oviparous organisms) like in humans. Humans embryos are able to get their
nourishment directly from their mothers in the womb (through the placenta)
hence don’t require a yolk (viviparous organisms).
The Eocene is the answer. Hope this helps.

Embryo- An unborn or unhatched offspring in the process of development, in particular a human offspring during the period from approximately the second to the eighth week after fertilization (after which it is usually termed a fetus).
Similarities and differences-
comparative embryology consist in the observation and the comparison of the embryonic development in various organisms
Similarities and differences between each modes of developments help scientists understand how the diversity of the animals happened
