A recently discovered 220-million year old fossil, Odontochelys semitestacea, is further evidence of evolution. This new species of turtle had a fully formed shell on its underside, but only a small partial shell on its back, extending from its backbone.
Scientists had long debated how the turtle shell evolved. As well as a partial shell, Odontochelys semitestaceaalso had ribs that had begun to widen, thus demonstrating that the fully developed shell of later turtles evolved from the ribs of earlier species.
Odontochelys semitestacea is one more piece in the jigsaw that shows conclusively how life on Earth evolved from earlier species.

Is the fossil record valid evidence for evolution?
Fossils provide amazing evidence for the theory of evolution and the long history of life on Earth.
What was Darwin's evidence for evolution?
Monkeys
Why are adaptations evidence of evolution?
Because adaptations are an observed effect of evolution. They could not happen if evolution did not occur.
What evidence is there for plant evolution?
Fossils, primarilly and nonspecifically.
What part of a whale is evidence for evolution?
The vestigial leg bones.
Why do scientists believe evolution occurred?
Charles Darwin developed the Theory of Evolution by Natural Selection before most of the fossil evidence for the theory existed. He looked at the micro-evolution practised by pigeon breeders, the evidence on the Galapagos Islands and elsewhere, and realised that evolution was the only explanation that made sense. He saw that related species were to be found in close proximity, evidence of evolution from a single parent species, whereas a single act of Special Creation ought to have placed the species anywhere on the globe where the environment was suitable.The fossil record shows clear evidence of evolution over a period of more than a billion years. Certainly, at first, there were no transitional species among the many species that had been found, although scientists saw much that did confirm the Theory of Evolution. That has changed, because many transitional species have been found. A recently discovered 220-million year old fossil, Odontochelys semitestacea, is a new species of turtle that had a fully formed shell on its underside, but only a small partial shell on its back, extending from its backbone. As well as a partial shell, Odontochelys semitestaceaalso had ribs that had begun to widen, thus demonstrating that the fully developed shell of later turtles evolved from the ribs of earlier species. Tiktaalik roseae is the name of a newly discovered lobe-finned fossil fish from the late Devonian period, that is a transitional form to amphibians, with basic wrist bones and simple fingers, as well as the robust ribcage necessitated by existence out of water. Odontochelys semitestacea and Tiktaalik roseae are two more pieces in the jigsaw that shows conclusively how life on Earth evolved from earlier species.Scientists can now use DNA evidence from modern species to support the fossil record, as further evidence of evolution.
When was Odontochelys created?
Odontochelys was created in 2008.
Is there any new evidence for Evolution?
Here are some recent discoveries that provide further, compelling evidence for evolution:Tiktaalik roseae is the name of a newly discovered lobe-finned fossil fish from the late Devonian period, that is a transitional form to amphibians. It had basic wrist bones and simple fingers, as well as the robust ribcage necessitated by existence out of water. There would be no conceivable explanation for Tiktaalik other than evolution.Another example of a clearly transitional species is the 380 million-year-old fossil of a primitive fish, Gogonasus. It had fins strong enough to support its weight in shallow water and propel itself along. A scan of the fossil, using a three-dimensional X-ray microscope, revealed its skeleton had several features that were more like those of a four-legged land animal, or tetrapod, than a fish. They included the structure of its middle ear and the existence of precursors of the forearm bones in its fins: the radius and ulna. Here was a fish that had already evolved to a point where it had much in common with later land animals.A recently discovered 220-million year old fossil, Odontochelys semitestacea, is further evidence of evolution.

What is indirect evidence?
Indirect evidence refers to information that requires some form of inference or interpretation to establish a connection to a particular fact or conclusion. It does not directly prove a point but rather provides clues or support for a theory or argument. Examples include circumstantial evidence or expert opinions.
Is similarities an early development not evidence for evolution?
It does hint at common ancestry so it is "evidence" of evolution.
Homology is evidence of what?
Evolution
What is the study of vertebrate forelimbs is related to what evidence?
In evolution the study of vertebrate forelimbs is related to the anatomical evidence from homology.
What evidence do we have for local adaptation?
how does adaptations give evidence for evolution?
In evolution the study of vertebrate forelimbs is related to evidence?
In evolution the study of vertebrate forelimbs is related to the anatomical evidence from homology.

What physical evidence would scientists expect to find if evolution were true?
They would expect to find, and have found:Related species should be found in close proximity if they evolved from a single parent species, whereas a single act of Special Creation ought to have placed the species anywhere on the globe where the environment was suitableEvidence that the evolution of some species is consistent with known environmental changes, such as climatic changes or the gradual drift of the Galapagos Islands away from their volcanic source.Evidence for evolution in DNAConsistent evidence in the fossil record of new species replacing older species, with adaptationsAlthough there may have been a few catastrophic periods in the fossil record when large numbers of species suddenly became extinct (known as "Great Extinctions") many localised extinctions should also have occurred whenever species could no longer adapt to new challengesTransitional species in the fossil record, such as the recently discovered Odontochelys semitestacea, a newly identified species of turtle from 220-million years ago, that had a fully formed shell on its underside, but only a small partial shell on its back, extending from its backbone.
