Are whale flippers and fish fins homologous?
Are whale flippers and fish fins homologous?
Fins of fish and flippers of whales are analogous organs. They perform the same function but they have different basic structure.
What are the similarities and differences between whale flippers and flukes and fish fins?
The whale’s flipper and tail flukes and fish fins are analogous structure as they have different structural formation but they perform the same function. Flipper and tails are locomotory organs in the whale and helps the whale in propelling similarly fins in the fish assist the fish in swimming.
What is a possible evolutionary explanation for how the skeletons can be similar but have different functions?
HOMOLOGOUS STRUCTURES Offer a possible evolutionary explanation for how the skeletons can be similar but the functions very different in each of the animals.
What are the evidence of evolution quizlet?
The major pieces of evidence for this theory can be broken down into the fossil record, embryology, comparative anatomy, and molecular biology – the basis of evolution.
What evidence for evolution is the most reliable?
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.
How does the fossil record supports the theory of evolution quizlet?
The fossil record is a sequence of once-living organisms found as fossils in different layers of Earth’s crust. The fossil record is made up of all of the fossils ever found. The fossil record supports evolution by showing the changes in different species over time. You just studied 11 terms!
Which of the following is the best evidence for evolution?
DNA sequence similarities are the strongest evidence for evolution from a common ancestor.
What can evolution not explain?
Evolution can’t explain complex organs Organs that allow detection of light could then have been favoured by natural selection, even if it did not provide full vision. These ideas have been proven correct many years later by researchers studying primitive light-sensing organs in animals.
Is Darwin theory wrong?
What Darwin Got Wrong is a 2010 book by philosopher Jerry Fodor and cognitive scientist Massimo Piattelli-Palmarini, in which the authors criticize Charles Darwin’s theory of natural selection. It is an extension of an argument first presented as “Why Pigs Don’t Have Wings” in the London Review of Books.
What did Darwin believe about evolution?
Charles Darwin was a British naturalist who proposed the theory of biological evolution by natural selection. Darwin defined evolution as “descent with modification,” the idea that species change over time, give rise to new species, and share a common ancestor.
What did Lamarck believe about evolution?
Unlike Darwin, Lamarck believed that living things evolved in a continuously upward direction, from dead matter, through simple to more complex forms, toward human “perfection.” Species didn’t die out in extinctions, Lamarck claimed. Instead, they changed into other species.
Who came up with the theory of evolution?
Charles Darwin
What are the other theories of evolution?
