Chapter 32 – An Introduction to Animal Diversity All animals share a common ancestor‚ sponges are basal animals‚ eumetazoa is a clade of animals with true tissues‚ most animal phyla belong to the clade bilateria‚ and vertebrates and some other phyla belong Animals share a unique homeobox-containing family of genes‚ known as the Hox genes‚ suggesting that this gene family evolved in the eukaryote lineage that gave rise to animals. Hox genes play important roles in the development of animal embryos

Organ Systems Project (Digestive‚ Excretory‚ Circulatory‚ Reproductive‚ Nervous) There is an enormous variety of life on our planet Earth ranging from simple cell bacteria to complex multicellular animals. Animals are creatures in the kingdom Animilia‚ one of the kingdoms in Whitakers 5 kingdom system. Their bodies consist of 555tanimal eukaryotic cells. Meaning their cell or cells contain a nucleus‚ are surrounded by a cell membrane (phospholipid bilayer) and can self-reproduce in a free
