or:en.wikipedia.org/wiki/Amphibian#Evolutionary_historyIchthyostega was one of the first primitive amphibians. Though undoubtedly of amphibian build and habit, it is not considered a true member of the group in the narrow sense, as the first true amphibians appeared in the Carboniferous period.en.wikipedia.org/wiki/IchthyostegaCarboniferous amphibians were diverse and common by the middle of the period, more so than they are today; some were as long as 6 meters, and those fully terrestrial as adults had scaly skin.[29] They included a number of basal tetrapod groups classified in early books under the Labyrinthodontia. These had long bodies, a head covered with bony plates and generally weak or undeveloped limbs. The largest were over 2 meters long. They were accompanied by an assemblage of smaller amphibians included under the Lepospondyli, often only about 15 cm (6 in) long. Some Carboniferous amphibians were aquatic and lived in rivers (Loxomma, Eogyrinus, Proterogyrinus); others may have been semi-aquatic (Ophiderpeton, Amphibamus, Hyloplesion) or terrestrial (Dendrerpeton, Tuditanus, Anthracosaurus).en.wikipedia.org/wiki/Carboniferous#TetrapodsThe labyrintodonts have their origin in the early middle Devonian (398-392 Mya) or possibly earlier. They evolved from a bony fish group: the fleshy-finned Rhipidistia. The only other living group of Rhipidistans alive today are the lungfish, the sister group of the landliving vertebrates. Earliest traces of the land-living forms are fossil trackways from Zache\u0142mie quarry, Poland, dated to 395 million years ago, attributed to an animal with feet very similar to Ichthyostega.en.wikipedia.org/wiki/Labyrinthodontia#Evolutionary_history
or:It was the backbone that distinguished the fish from the invertebrates. This backbone would have had to undergo major modifications for the fish to become amphibian, that is, a creature that could live both in the water and on land. A pelvis had to be added, but no fossil fish are known that show how the pelvis of amphibians developed. In some amphibians, such as frogs and toads, the entire backbone would have had to change beyond recognition. Also, skull bones are different. In addition, in the forming of amphibians, evolution requires fish fins to become jointed limbs with wrists and toes, accompanied by major alterations in muscles and nerves. Gills must change to lungs. In fish, blood is pumped by a two-chambered heart, but in amphibians by a three-chambered heart.\"\u202fAnd God created the great sea creatures and all living creatures that move and swarm in the waters according to their kinds and every winged flying creature according to its kind. And God saw that it was good. 22\u202fWith that God blessed them, saying: \u201cBe fruitful and become many and fill the waters of the sea, and let the flying creatures become many in the earth.\u201d 23\u202fAnd there was evening and there was morning, a fifth day\".Genesis 1:20. Evolution theory has no facts compared to the bible's when it comes to creation.For more information on this subjects and others, please go to jw.org \"Online Library\" Also for free downloads, publications or read online.
