I'm wondering the same thing! But not how, but when?!
Hox genes are responsible for controlling the development of body segments in animals. Changes in the expression of Hox genes can lead to modifications in body segment patterning, leading to the diverse body plans seen in animals. Therefore, variations in Hox gene expression among different species contribute to the diversity of animal body plans.
No, the majority of animal embryos develop outside the mother's body. This includes animals such as birds, reptiles, and most fish. Embryos that develop inside the mother's body are found in live-bearing mammals as well as some fish and sharks.
Two features defining the animal phyla are adult body plans and patterns of embryological development.
The major animal body plans seen today appeared in the fossil record over 500 million years ago at the beginning of the Cambrian Period. This period is known as the Cambrian Explosion, during which a wide variety of animal forms emerged and diversified rapidly.
The majority of glycogen is stored in the liver and muscles in the body.
you can tell if an animal have bilateral symmetry if you cut the animal in half, (hypothetically) and both sides are the same
The majority of our body's phosphorus is stored in our bones and teeth. It plays a crucial role in bone mineralization and structure.
The element that makes up the majority of the human body is oxygen.
Pimples can appear anywhere on your body. Pimples can appear anywhere on your body.
Invertebrates are animals that do not have a backbone or spinal column. They make up the vast majority of animal species on Earth and include groups such as insects, mollusks, and worms.
