Homo (from Latin homō 'man') is the genus that emerged in the (otherwise extinct) genus Australopithecus that encompasses the extant species Homo sapiens (modern humans), plus several extinct species classified as either ancestral to or closely related to modern humans (depending on the species), most notably Homo erectus and Homo genus emerged with the .   Artur Debat / Getty Images. The first true vertebrates on Earth, fish evolved from invertebrate ancestors about million years ago and have dominated the world's oceans, lakes, and rivers ever since. There are three main types of fish: bony fish, which includes such familiar species as tuna and salmon; cartilaginous fish, which includes sharks, rays, and skates; and jawless fish, a small. One example of a plant genus containing many species is Rosa, which contains more than species of contrast, the genus Ginkgo is monotypic, containing only the common ginkgo (also called the maidenhair tree). Among animals, for example, the species of horses and zebras form the genus Equus, whereas the hawksbill sea turtle is the only member of the genus Eretmochelys.   Although there are innumerable combinations, for simplification we will list the six general reproduction methods listed by silviculturist D.M. Smith in his book, The Practice of Silviculture. Smith's book has been studied by foresters for decades and used as a proven, practical and widely accepted guide at the point where a timber harvest is.

Type Species of Paleozoic Nuculoid Bivalve Genera by Mcalester, A.l. at Pemberley Books. The complex idea of species has evolved over time, yet its meaning is far from resolved.

This comprehensive work takes a fresh look at an idea central to the field of biology by tracing its history from antiquity to today. John S. Wilkins explores the essentialist view, a staple of logic from Plato and Aristotle through the Middle Ages to fairly recent times, and considers the idea of species.
