What Is The Oldest Body Fossil? A spongelike structure discovered in exposed 890-million-year-old rock in Canada’s Northwest Territories may be the oldest known fossilized animal body, according to a study whose findings will likely add another controversy to longstanding debates about the planet’s earliest animal life. Whats the oldest fossil? Stromatolites are the oldest known
What Is The Origin Of Life On Earth? We know that life on Earth is built around compounds that contain elements such as carbon, nitrogen, hydrogen and oxygen. … The first traces of life recorded on Earth are thought to be as old as 4.2 billion years, indicating that life may have evolved within 200
What Hominin Species Was Found At The Site Of Atapuerca In Northern Spain? Atapuerca, site of several limestone caves near Burgos in northern Spain, known for the abundant human (genus Homo) remains discovered there beginning in 1976. What specie was found in the pit of bones in Atapuerca in northern Spain? Cranium 5. The mandible
What Is The Key Observational Evidence That Supports The Idea That Life On Earth Has Evolved Through Time? What is the key observational evidence that supports the idea that life on Earth has evolved through time? The fossil record, revealed in geological layers of different ages, shows that life on Earth has become more complex
What Era Is Sometimes Called The Age Of Fish Or Ancient Life? The Devonian, part of the Paleozoic era What era were fish alive? The evolution of fish began about 530 million years ago during the Cambrian explosion. It was during this time that the early chordates developed the skull and the vertebral column, leading
How Does Comparing Skeletons Of These Animals Provide Support For The Scientific Theory Of Evolution? How does comparing the skeletons of these animals provide support for the scientific theory of evolution? It provides information about the organisms’ habitats. It shows possible common ancestry between organisms. … It shows possible chromosomal similarities between organisms. How do
What Is Carbon Dating And How Is It Used? Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. What is carbon dating where it is used? It has proved
During Which Era Was The Great Cambrian Explosion? Cambrian explosion, the unparalleled emergence of organisms between 541 million and approximately 530 million years ago at the beginning of the Cambrian Period. The event was characterized by the appearance of many of the major phyla (between 20 and 35) that make up modern animal life. What
How Did The Camarasaurus Die? A fossil record exists of two adults and a 12.2-m-long (40 ft) juvenile that died together in the Late Jurassic epoch, around 150 million years ago (in northeast Wyoming, United States). Their bodies were assumed to be washed by a river in spate (flood) to their final resting place in
How Can Carbon 14 Be Used To Determine The Age Of Fossils? Radiocarbon decays slowly in a living organism, and the amount lost is continually replenished as long as the organism takes in air or food. … Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can
