Odontochelys semitestacea |
|
Odontochelys semitestacea is currently the oldest known
species of turtle.
It lived in the
Triassic period
about 220 million years ago - in shallow marine environments -
fossils have
been found in
China.
Odontochelys had a number of primitive features that distinguish
it from modern turtles. These include teeth in its upper and lower
jaws (modern turtles have a beak and no teeth), and only the lower
half (the "plastron") of a turtle's armor. It also had
an elongated skull and tail.
Odontochelys was an early turtle that lived about 220 million years ago

Richard Dawkins transformed our view of God in his blockbuster, The God Delusion, which sold more than 2 million copies in English alone. He revolutionized the way we see natural selection in the seminal bestseller The Selfish Gene. Now, he launches a fierce counterattack against proponents of "Intelligent Design" in his latest New York Times bestseller, The Greatest Show on Earth. "Intelligent Design" is being taught in our schools; educators are being asked to "teach the controversy" behind evolutionary theory. There is no controversy. Dawkins sifts through rich layers of scientific evidence—from living examples of natural selection to clues in the fossil record; from natural clocks that mark the vast epochs wherein evolution ran its course to the intricacies of developing embryos; from plate tectonics to molecular genetics—to make the airtight case that "we find ourselves perched on one tiny twig in the midst of a blossoming and flourishing tree of life and it is no accident, but the direct consequence of evolution by non-random selection." His unjaded passion for the natural world turns what might have been a negative argument, exposing the absurdities of the creationist position, into a positive offering to the reader: nothing less than a master’s vision of life, in all its splendor. |

How can we bring together the study of genes, embryos and fossils? Embryos in Deep Time is a critical synthesis of the study of individual development in fossils. It brings together an up-to-date review of concepts from comparative anatomy, ecology and developmental genetics, and examples of different kinds of animals from diverse geological epochs and geographic areas.
Can fossil embryos demonstrate evolutionary changes in reproductive modes? How have changes in ocean chemistry in the past affected the development of marine organisms? What can the microstructure of fossil bone and teeth reveal about maturation time, longevity and changes in growth phases? This book addresses these and other issues and documents with numerous examples and illustrations how fossils provide evidence not only of adult anatomy but also of the life history of individuals at different growth stages. The central topic of Biology today--the transformations occurring during the life of an organism and the mechanisms behind them--is addressed in an integrative manner for extinct animals. |

They must be gullible to believe something that cannot be proven. They are easily led and can be made to believe things not supported by fact. They are victims of rules that stifle creativity. They are judgmental, with a "holier than thou" attitude. Who are "they"? To some people, "they" are Christians, and the statements represent issues people have with Christianity. In Christians Can't Lose, author Gregg George sets the record straight. He writes about the many issues people have against Christianity and explains why Christians believe what they do. He calls on skeptics to keep an open mind about a Christian's belief in God because supposed evidence to the contrary may not be as compelling as they think. George also calls on Christians to behave in a way that magnifies the Lord and shows the world the true love of Christ. He presents a case for believing in God simply because a believer cannot lose. Even if God does not exist, a Christian loses nothing for his belief. However, if God really does exist, a Christian will gain eternal life with God, while a nonbeliever will suffer eternal banishment from the presence of God. The choice should be quite simple. Christians Can't Lose will help nonbelievers learn more about what Christians believe and who they are. For Christians, the author reminds them how to be an effective role model and God's representative on earth. It is about understanding-on both sides of the belief coin. |
