Are sharks? Answers. How do we know that these similarities are because of convergent evolution? How do we know those characters are common to all vertebrates? It looks much like a dog, but has stripes on its back like a tiger, and resembles a large cat, a fox, or a wolf. 0 0 Comment. Sharks and whales both have streamlined bodies and tail flukes. ORDER PAPER NOW Hint: Whales are tetrapods. How do we know that sharks and whales similarities because of convergent evolution . But macro-evolution has to be inferred as a mechanism because it can’t be duplicated or measured. Now that we know which specific morphological features are convergent we have the opportunity to pin down the adaptive significance of these modifications by examining behavior and function in a comparative context. When two groups of organisms independently evolve similar adaptations, it's called convergent evolution. Hint: Whales are tetrapods. How do we know that these similarities are because of convergent evolution? How do we know that sharks and whales similarities because of convergent evolution - 10618541 1. Analogy, or analogous structures, is actually the one that does not indicate there is a recent common ancestor between two organisms. Many of the similarities are a product of convergent evolution, animals from different lineages that evolve similar morphological and physiological characteristics because they endure the same environmental contraints. This is called parallel or convergent evolution Convergent similarities are not from BIOLOGY Biol at University Of Georgia We use homologous characters — characters in different organisms that are similar because they were inherited from a common ancestor that also had that character. Ask your question. What do we know about that common ancestor? Catie Leary ... What do all these creatures have in common? Join now. Are sharks? Here is a brief account of convergent evolution vs. divergent evolution. When two groups of organisms independently evolve similar adaptations, it’s called convergent evolution.

We have your A+++ dream Grade Essay, custom written, Plagiarism free and delivered right Bird and bat wings are analogous — that is, they have separate evolutionary origins, but are superficially similar because they have both experienced natural selection that shaped them to play a key role in flight. It was once thought extinct, but some recent sightings have been reported in the news. our writers can offer a custom paper based on these or other instructions. Sharks and whales both have streamlined bodies and tail flukes. FIGURE 19 . Edit. So you can see why evolutionists might presume that the rules of our universe constrain what’s possible for physical development and functions; some yet-undefined rules produce similar designs over and over. Log in. The Evolution Lab MISSION 3 MISSION 3 DNA Spells Evolution Introductory video: Since its discovery in 1953, DNA has revolutionized the study of evolutionary relationships. When two groups of organisms independently evolve similar adaptations, it’s called convergent evolution. It’s an idea called convergent evolution. Evolutionary theory is based on the ASSUMPTION that different forms of life are similar because they arose from a common ancestor.
