Be detailed in your answers and address each aspect of the theme. It is said that plants are good paleoclimatic indicators. Please explain, and give specific examples to support your response. The DNA of prokaryotes is enclosed within a nuclear membrane. A long, narrow wing is aerodynamically efficient but is difficult and energy consuming to flap.
Long wings are therefore most suitable to animals that live and fly in forests.
Populations of Homo habilis overlapped with those of Homo erectus. Most of the trees in tropical rainforests are reseeded by wind dispersal. This cold current prevented a warm current from reaching the coast of Antarctica and Antarctica subsequently cooled. As a result, cold water in the vicinity began to descend to the deep sea and thermohaline conditions were initiated. The limit of articulation of the limb is much greater in the amphibians than in the fish.
