[5] Like other contemporary researchers of his time, Haeckel adopted his terminology from Carl Linnaeus where human ecological connections were more evident. In his 1749 publication, Specimen academicum de oeconomia naturae, Linnaeus developed a science that included the economy and polis of nature. Polis stems from its Greek roots for a ...
The process of selective breeding, in which organisms with desired traits (and thus with the desired genes) are used to breed the next generation and organisms lacking the trait are not bred, is a precursor to the modern concept of genetic modification [20]: 1 Various advancements in genetics allowed humans to directly alter the DNA and ...
All modern humans are classified into the species Homo sapiens, coined by Carl Linnaeus in his 1735 work Systema Naturae. [4] The generic name Homo is a learned 18th-century derivation from Latin homō, which refers to humans of either sex. [5] [6] The word human can refer to all members of the Homo genus. [7]
The Late Upper Paleolithic Model, or Upper Paleolithic Revolution, refers to the idea that, though anatomically modern humans first appear around 150,000 years ago (as was once believed), they were not cognitively or behaviorally "modern" until around 50,000 years ago, leading to their expansion out of Africa and into Europe and Asia.
Homo (from Latin homō ' human ') is a genus of great ape (family Hominidae) that emerged from the genus Australopithecus and encompasses only a single extant species, Homo sapiens (modern humans), along with a number of extinct species (collectively called archaic humans) classified as either ancestral or closely related to modern humans; these include Homo erectus and Homo neanderthalensis.
The ZW sex-determination system is a chromosomal system that determines the sex of offspring in birds, some fish and crustaceans such as the giant river prawn, some insects (including butterflies and moths), the schistosome family of flatworms, and some reptiles, e.g. majority of snakes, lacertid lizards and monitors, including Komodo dragons.
In one sense, the first modern ethologist was Charles Darwin, whose 1872 book The Expression of the Emotions in Man and Animals influenced many ethologists. He pursued his interest in behaviour by encouraging his protégé George Romanes , who investigated animal learning and intelligence using an anthropomorphic method, anecdotal cognitivism ...
The first chapter introduces us to the extreme human-centred view of the natural world in early modern England. This view had theological foundations and roots in Greek philosophers such as Aristotle. All things were created for the benefit and pleasure of man. Wild animals, birds and fish are God's gift to all men.
