Who is turtle dating

This phylogenetic problem has remained unsolved partly because turtles have such a unique morphology that only few characters can be used to link them with any other group of amniotes.’ Because of the lack of fossil intermediates, evolutionists have to resort to speculative hypotheses to rescue to fit turtles into evolution.One hypothesis is that the turtle carapace gradually evolved from ‘elements of the primitive reptilian integument.’ have proposed a theoretical embryological model involving movement of the ribs into the dermal layer leading to the evolution of a turtle shell.One theory is that sea turtles evolved from land turtles, requiring significant evolutionary changes to adapt to the sea.For example, sea turtles filter salt from sea water by producing large salty tears.

We wish to thank Eric Blievernicht, Jody Allen and Clifford Lillo for their helpful comments.but also to molecular systematists to resolve these conflicts.’ Increasing research has tended to uncover more conflicts between molecular and gross morphological data as time passes.Turtles are an ideal life form for evaluating the evidence for evolution, not only because their shells are readily preserved but also because of the abundance of turtles in the fossil record.concluded that the ‘absence of intermediates or transitional forms in the fossil record’, especially when the fossil record is coupled with the developmental and anatomical novelties exhibited by turtles, argues that turtles arose saltationally.

Flank concludes that ‘Turtle fossils are found more often than other animals of similar size, and the evolutionary history of the modern turtle is fairly well known’ except the earliest turtle ancestors and, as a result, ‘the exact ancestry of living turtles is disputed among paleontologists.’ Another question evolutionists are unable to answer is: did the various families of chelonians evolve from some common ancestor or by parallel or convergent evolution?

This modeling, although useful, cannot replace the need for paleontological evidence.
