When it comes to origins science, facts are selected to fit the presuppositions of the scientists' worldview. When the facts do not fit, excuses are made, masquerading as valid scientific theories or hypotheses. These excuses are vague, and even laughable. Especially when some evolutionists insist that dinosaurs evolved into birds.
Birds and dinosaurs have oval eggs and big eyes. Does this necessarily mean they evolved from a common ancestor?
Hopeful ovals: Intent on evolving sparrows out of T. rex kin, some paleontologists are selectively basing arguments for common ancestry on similarities that do not seem all that impressive. For instance, a report on PhysOrg allowed researchers from Barcelona to claim common ancestry based on oval egg shape. “Researchers from Spain identified in Lleida a series of dinosaur eggs with a unique characteristic: They are oval in shape,” the subtitle announced. “The discovery represents proof in favor of the hypothesis that birds and non avian theropods, dinosaurs from the Cretaceous Period, could have a common ancestor.” The reporter later downgraded from proof to the milder phrase that it “suggests a connection with bird eggs.” If such a shape had been found in an unrelated animal group’s eggs, Darwinists would have undoubtedly attributed it to “convergent evolution.”
Peter Pan evolution: Nature on July 12 declared that “Birds have paedomorphic dinosaur skulls” (paedomorphic referring to “retaining a morphology as adults that resembles that of the juveniles or embryos of most other archosaurs”). The team of Bullar et al. (Nature 487, 12 July 2012, pp. 223–226, doi:10.1038/nature11146) performed detailed measurements of skulls of birds and theropods, and hypothesized that bird skulls represent a stage of arrested development of dinosaur skulls. Are they implying that a dinosaur didn’t finish maturing, and became a bird instead? Apparently so, and don’t think for a minute that we humans are exempt from this kind of hypothesis. They added, “Heterochrony—change in the timing or rate of developmental events—has been implicated in the evolution of major vertebrate lineages such as mammals, including humans.”Read the rest of "Birdifying Dinosaurs", as well as an interesting exercise, here.
