Q: Passage: The first amniotes apparently arose in the Late Carboniferous. They descended from earlier reptiliomorph amphibious tetrapods, which lived on land that was already inhabited by insects and other invertebrates as well as by ferns, mosses and other plants. Within a few million years, two important amniote lineages became distinct: the synapsids, which would later include the common ancestor of the mammals; and the sauropsids, which would eventually come to include turtles, lizards, snakes, crocodilians, dinosaurs and birds. Synapsids have a single hole (temporal fenestra) low on each side of the skull.

A: From what period did the first insects come from?

Q: Passage: Although anthropologists worldwide refer to Tylor's definition of culture, in the 20th century "culture" emerged as the central and unifying concept of American anthropology, where it most commonly refers to the universal human capacity to classify and encode human experiences symbolically, and to communicate symbolically encoded experiences socially.[citation needed] American anthropology is organized into four fields, each of which plays an important role in research on culture: biological anthropology, linguistic anthropology, cultural anthropology, and archaeology.

A: Who's definition of culture did anthropologists reject?

Within the county, population density ranges 0.5 in West Somerset to 2.2 persons per hectare in Taunton Deane. The percentage of the population who are economically active is higher than the regional and national average, and the unemployment rate is lower than the regional and national average.
