What Is The Importance Of Tiktaalik Roseae To The Study Of Evolution? The discovery of well-preserved pelves and a partial pelvic fin from Tiktaalik roseae, a 375 million-year-old transitional species between fish and the first legged animals, reveals that the evolution of hind legs actually began as enhanced hind fins. Why is the Tiktaalik roseae
What Is The Land Like Where Mesosaurus Fossils Are Found Quizlet? What is the land like where the Mesosaurus fossils are found? The fossils are found in both South America and Africa, about 4,000km apart. Why are the Mesosaurus fossils separated by 4000 km of ocean? This means that these plates, and the continents on
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 Does The Presence Of Mesosaurus Fossils Tell Us? The Mesosaurus fossils tell us that South America, Africa and Antarctica were once connected because it is impossible for these reptiles to swim over the vast oceans and move from one continent to another. What does Mesosaurus indicate? Mesosaurus (meaning “middle lizard”) is an extinct genus
What Is Considered The Most Powerful Form Of Evidence Of Evolution? Perhaps the most persuasive fossil evidence for evolution is the consistency of the sequence of fossils from early to recent. Nowhere on Earth do we find, for example, mammals in Devonian (the age of fishes) strata, or human fossils coexisting with dinosaur remains. Which

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.
