Crustaceae. Because of this information the scientist has came to a conclusion that Metazoa started way before Cambrian period. Although back than it was invisible. How did they get this idea? Well they got this based on the study of putative trace fossils. In addition there was frustration to this idea because they wondered why fossilizable forms of various phyla appeared almost simultaneously and wrong. This means that there was some mistake that the scientist has made with their hypothesis about

natural selection occurred in step-wise fashion. Assignment Write 3–4 pages on the following (not including the title and reference pages): •Explain the concepts of phyletic gradualism and punctuated equilibrium. •What predictions about the fossil record does punctuated equilibrium make? •In this model‚ what are the processes that produce rapid evolution? Which evolutionary factors are responsible for the periods of relative stasis? •Patterns of punctuated equilibrium have been observed in

qualify these units as Early‚ Mid‚ and Late when referring to time‚ and Lower‚ Middle‚ and Upper when referring to the corresponding rocks. Geologic units from the same time but different parts of the world often look different and contain different fossils‚ so the same period was historically given different names in different locales. To describe the geologic time‚ scientists use the geologic time scale‚ which is a system of chronological measurement that relates stratigraphy to time. Objective

The pterodactyl is the most well known member of the pterosaur family. The pterodactyl was a flying dinosaur that was a predator and carnivore. The pterodactyl was much like a raptor in today’s age. It ate fish and other small animals like small reptiles and other small mammals. The pterodactyl was alive during the late jurassic epoch. It lived on many different continents. It lived in Europe‚ Australia‚ North America‚ and Africa. The pterodactyl was one of the smaller members of the pterosaur family

Can scientific evidence prove there is a personal concerned‚ God outside the universe? Lee Strobel very early in his teenage years decided that based on the evolutionary thought of Darwin and later others prominent theology‚ there could not be a God who loved humans personally and created a universe by design. He went on to college where he became a sincere atheist. However he could not remain content there for long because as he admits he was always searching for answers as his career in journalism

Of all the species that have existed on Earth 99 percent have gone extinct and even fewer make it into the fossil record and a very small fraction of those that fossilize are actually found even partially complete. Even if all of them did fossilize many would be too hard dig for many of them. And also it is highly unlikely that most would be found complete‚ due to the number of natural disasters and processes that have happened from the animal’s death to whenever it is discovered. Natural disasters

years earlier than the previously oldest known dinosaurs‚ and could change researchers’ views of how they evolved. The scientists published their findings in the journal Biology Letters. Some scientists‚ including the authors‚ caution that the fossils could also represent a close relative to dinosaurs. The earliest dinosaurs were probably Eoraptor and Eodromaeus‚ which were true dinosaurs‚ and lived in what was Argentina 230 million years ago. In 2010‚ Sterling Nesbitt‚ a paleontologist at

The Origin of the Earth‚ One of God’s Hidden Secrets “Much of geology is pure speculation and is as such on the same basis as philosophy‚ or must be accepted on faith‚ as the truths of theology” (Rehwinkel 177). For geologists this means that any theory of how the Earth‚ atmosphere and life originated‚ takes faith to believe‚ whether it is the evolutionist’s view or the creationist’s view. Creationists believe that the Earth was created 6000-7000 years ago. This number is based on what the Bible

Are you fascinated by dinosaurs or do you play many dinosaur games? Well guess what they might actually be all around us and they might not be as destructive as many of us think of them as. Dinosaurs ruled the our planet for millions of years‚ and they have been believed to go extinct by many humans. But the truth is that modern versions of dinosaurs are all around us. Scientists have been observing common features between the two species‚ and research shows that these animals are linked. The new
