Taking the groups in what is now generally considered to be their broad chronological sequence, the first are the "animal finials", with two rampant confronted animals, generally a pair of large-horned ibex (or goats or mouflon sheep) or felines, facing each other with a central tube or open rings (formed at the junctions of their front and hind feet) between them. The bezoar ibex ("capra aegagrus aegagrusis"), the local wild species of goat or ibex, was already domesticated millennia before; it has large curved horns with knobbly ribs. Compared to later types, the animals are more naturalistic,
Taxonomy of wheat the fertile crescent of the Near East. All the other species are domesticated. Although relatively few genes control domestication, and wild and domesticated forms are interfertile, wild and domesticated wheats occupy entirely separate habitats. Traditional classification gives more weight to domesticated status. All wild wheats are hulled: they have tough glumes (husks) that tightly enclose the grains. Each "package" of glumes, lemma and palaea, and grain(s) is known as a spikelet. At maturity the rachis (central stalk of the cereal ear) disarticulates, allowing the spikelets to disperse. The first domesticated wheats, einkorn and emmer, were hulled like their wild ancestors,
