The lack of association between amphibian and fish is related to the evolutionary history of Tiktaalik fossil mammalian Darwinian theory. Contact information is there. The rocks that the author and his colleagues have investigated are sedimentary rocks, most commonly found in rivers and oceans. Fossils of Tiktaalik have fin and scales, flexible neck, flat head, and complex bone structure.

The first batch of amphibian appeared about 350 million years ago. According to the frog you think, the first frog appeared in Jurassic about 200 million years ago in Triassic or 180 million years ago. Amphibian - the word comes from the Greek "amphi" and "bios" (to live a double life) - a bridge between aquatic and land, a connection between fish and reptiles. They include salamanders as well as frogs and toads. Reptiles did not do a good job in public relations for their creatures; Linnae's attitude to the frog has been inherited for centuries. Smith College Stephen Tilly said: "The popular concept is that they are not well acclimated, low vertebrates are garbage rooted in the vision of ancient evolution." Complicated behavior, anatomy, physiology and reproductive patterns. "

Vertebrates moved to land during the Devonian period, about 380 million years ago. The scales are amphibious animals, one of the earliest terrestrial vertebrates. It is derived from Greenland fish and found in Greenland, known as Rhipidistians. Amphibians produce reptiles. Reptiles have evolved scales to reduce water loss, and shelled eggs that allow young birds to hatch on land. The earliest well-preserved reptile was a rock from Hylonomus, Nova Scotia. The extinction of the Permanent was the greatest extinction in history. It took place about 250 million years ago. The last of the Cambrian fauna has become extinct. Paleontimals have infiltrated about 50 families from about 300 families. It is estimated that 96% of species (50% of all households) achieved the target. After this incident, the modern fauna is gradually expanding since the Ordovician ship took over.
