The first amniotic egg-laying creatures are believed to be early reptiles, which evolved from amphibian ancestors during the Carboniferous period, around 320 million years ago. The development of the amniotic egg allowed these creatures to reproduce in a wider range of terrestrial environments, as the egg's protective membranes provided a moist environment for the embryo, preventing desiccation. This evolutionary advancement played a crucial role in the transition from water to land for vertebrates.

What mammals lay amniotic eggs?
Monotremes are egg-laying mammals. They include the platypus and echidna.
Does a squid have an amniotic egg?
No, squids do not have an amniotic egg. Amniotic eggs are characteristic of reptiles, birds, and some mammals, featuring a protective amniotic membrane. Squids belong to the class Cephalopoda and reproduce by laying eggs that are not amniotic; their eggs are typically encapsulated in a gelatinous mass and develop outside the mother's body.
What are two derived characteristics that allowed reptiles to become the first entirely terrestrial vertebrates?
Plato Users: A. Amniotic Egg, and Dry Scaly Skin.
How do eggs reproduce by laying their eggs?
Eggs don't reproduce. Whatever that's in the egg has to grow to a sexually mature creature first, in order to mate, and then lay eggs.
What kind of creature does the echidna come from?
The echidna does not come from any other creature. It is simply a member of an unusual egg-laying infraclass of mammals known as monotremes.
Do chondrichthyes have an amniotic egg?
No, chondrichthyes, which include sharks, rays, and skates, do not have an amniotic egg. Instead, many species of chondrichthyes reproduce through methods such as oviparity (laying eggs) or viviparity (live birth), with some species having adaptations like the development of embryos in a protective environment within the mother's body. The amniotic egg is characteristic of reptiles, birds, and some mammals, which allows for reproduction in terrestrial environments.
What is an example of an amniotic egg?

Which of the following is true about the amniotic egg?
The amniotic egg is a key evolutionary adaptation for reptiles, birds, and egg-laying mammals that allows for reproduction on land. It is surrounded by a protective membrane called the amnion, which helps prevent desiccation and provides a nutrient-rich environment for the developing embryo.
