teeth” (Shubin 60). So we derive from this that teeth can play an important role in the food chain and thus in evolution. However‚ teeth play a more important part than this. By studying the anatomy of teeth many secrets can be revealed about ancient reptiles and mammals. For instance‚ Shubin relates that “The bumps‚ pits and ridges on teeth often reflect the diet” (Shubin 60). By knowing the diet of an ancient creature‚ it is reasonable to see how a paleontologist and evolutionist can follow the emergence

adapted to different purposes as the result of descent with modification from a common ancestor. Similarities and differences among homologous structures help determine how recently species shared a common ancestor. For example the front limbs of reptiles and birds are more similar to each other than either is to the front limb of an mammal. This similarity indicates

either essential or mortal‚ depending on the species. Firstly‚ it is well-known that species that do not have the adequate habitat cannot survive or live a good life in captivity‚ like tigers that do not have enough space to recreate or cold-blooded reptiles that do not have the correct heating temperature in their terrariums. However‚ there are several species that do not have a single chance to survive in their natural habitat‚ like albino breeds of snakes or gorillas‚ for example. In those cases‚

Over the course of history‚ living organisms have shifted tremendously over time. However‚ it makes you wonder how they did it. History today‚ proves that it wasn’t the organisms themselves that inspired the change‚ but a series of multiple mass extinctions over time. Because of the extinctions‚ adaptations appeared‚ more need to evolve became apparent‚ and made it easier to evolve via the climate and environment. The first thing extinctions influenced was adaptations. As stated in the documentary

Plate tectonic theory is a widely excepted theory that the Earth’s lithosphere is made up of plates‚ both oceanic and continental‚ which slowly move due to convection currents in the mantle and the asthenosphere. However‚ it is very hard to be certain as we can’t see the structure of the Earth‚ so some people do not agree with it. This theory saw the introduction of what we know today to be tectonic plates. Tectonic plates occur where there is radioactive decay in the core and temperatures are extremely

To follow‚ the two have familiar settings‚ taking place in a jungle-like area where the protagonists are attacked by reptiles‚ a crocodile and Tyrannosaurus rex respectively. Finally‚ both contain similar plots‚ where the protagonists disobey orders‚ which puts them in harm’s path. With an overall summary of the novels completed‚ a look will be taken at the difference.

Dr. Curry-Roger’s talk was very interesting and had many different points throughout. The first interesting point mentioned was that dinosaurs are birds. Dr. Curry-Roger explained that both birds and dinosaurs had a lot in common. She stated that birds have feathers that are complex‚ a fused clavicle‚ short bony tails‚ bones that are filled with air sacs‚ efficient breathing‚ and a fast growth rate. When comparing fossils to birds‚ they had many of the same features. Some dinosaurs had feathers‚

He reveals the story of human evolution by tracing many parts of our body’s structure to many creatures that lived long ago‚ using both the fossil record and DNA evidence. Shubin showed us that our hands look like the fins of prehistoric fish‚ our skin‚ hair and teeth can be find to an early reptiles‚ most parts of our DNAs

resulted in the extinction of many species. Cuvier also described faunal succession in layers on sedimentary rock. He also identified the first pterosaur‚ which he named a pterodactyl‚ as well as the first monosaur. Georges speculated that giant reptiles were dominant vertebrates in a past era‚ and this speculation was not confirmed for more than two decades after his death. Cuvier said‚ "All of these facts‚ consistent among themselves‚ and not opposed by any report‚ seem to me to prove the existence
