Summary Introduction
To review:
The features of early development that are conserved across all vertebrates.
Introduction:
Early development of an organism includes three stages of development. These are cleavage, gastrulation, and neurulation. Cleavage begins as soon as the egg is fertilized. It includes the mitotic division of the zygote to produce gastrula. The gastrula undergoes gastrulation that leads to the formation of the germ layers by morphogenetic rearrangements of the cells.

What conclusion can be drawn from embryological development?
Insect and bird wings are similar in function but not in structure.
Paleontologists have used fossils to trace the evolution of the modern camel.
Many organisms have structures with no apparent function found during embryo
development.
The presence of gill slits and tails in early vertebrate embryos shows that they may
share a common ancestor.

How would you explain the similarities among bird, mammal, and reptile embryos at the early stages of development, and what directs the sequence of events during embryonic development?
Mammals have unique reproductive adaptations that have contributed to their evolutionary success. One of the distinguishing characteristics of mammals is their mammary glands, which allow for the production of milk. Even the more primitive mammals, such as the duck-billed platypus and the kangaroo, have some type of mammary glands. However, only the placental mammals (e.g. humans, horses, dogs) have a placenta, which supports the internal development of the embryo. The most primitive mammals have no placenta and can’t support the internal development of the embryo.
Describe one advantage for an offspring to develop internally as opposed to developing externally (this means inside vs. outside the female’s womb/body)
