“Dino-era Delivery At Sea”
By: Sid Perkins
Source: www.sciencenews.org

Reptiles that lived in the sea during the dinosaur-era evolved successfully because their ancestors decided the gender of the offspring by genetics other than incubation temperature. Now, there are about sixty species of sea snakes, which are the only reptiles to spend their entire lives underwater. They even give birth in the water. Reptiles such as turtles and crocodiles have to go to shore to lay eggs. But there is a huge difference between reptiles that are fully aquatic and the non-fully aquatic reptiles. With sea snakes the gender of their offspring is determined genetically, not by incubation temperature. Chris Organ an evolutionary

    Geology News Report

    The article in New York Times talks about the spacecraft that was sent into space 36 years ago and recently NASA was able to send a newer version of it into space. Voyage 1 was initially designed as a four-year mission to Saturn. It is the first spacecraft to exit our solar system. This will help scientists to explore the outside of our solar system. Voyage 1 stopped sending pictures however; it helped scientists to attain pictures of Saturn and Jupiter. Voyage 2 will be able to send better pictures and scientists expect it to exit our solar system in a few years. NASA has high hopes for the new and improved Voyage 2. By improving a spacecraft they will be able to get better samples and images of other planets further than Saturn and Jupiter and maybe even see what's outside of the solar system. They made a prediction that it will pass some stars and will be pulled by their gravity. I found this article interesting because nobody has yet seen what the outside of our solar system is like. Maybe NASA will be able to state some groundbreaking news from the new pictures that they will attain.…

Mr. Obama said that the United States aid agencies were moving swiftly to get help to Haiti and that search-and-rescue teams were en route. He described the reports of destruction as “truly heart-wrenching,” made more cruel given Haiti’s long-troubled circumstances. “This is a time when we are reminded of the common humanity that we all share,” Mr. Obama said.

    Leafy Sea Dragon

    Seadragons usually live a solitary life, but males and females come togeather to breed. The female lays up to 200 eggs at a time. The males are responsible for holding and protecting the eggs, But instead of a pouch male sea dragons have a spongy brood patch on the underside of the tail where females deposit her eggs during mating. The eggs are fertilized during the transfer. The males incubate the eggs and carry them till they’re ready to hatch, releasing miniature sea dragons into the water after about four to six weeks. They are independent from the moment they hatch. It only takes about two years for seadragons to reach full size and age where they can reproduce.…

    Chaos in Jurassic Park

    "They're breeding."(Crichton 164). Ian Malcolm had predicted that the dinosaurs of Jurassic Park were, in fact, breeding. This was discovered to be true later on in the book, when the numbers of dinosaurs were exceeding the expected count. The use of frog DNA to restore missing portions of dinosaur DNA was the underlying cause. It gave them the ability to reproduce by switching gender. Malcolm had said, "But life finds a way"(Crichton 160), early on in the trip to Jurassic Park, and as he had said, life truly did find a way. The very process of making certain that the dinosaurs were all female, thus unable to reproduce, through first, genetically engineering them to be female, and then irradiating them may have been the very reason why they did in fact reproduce. Any minuscule…

    Geology 270 Research Paper

    When it comes to choosing classes for a semester I always try to choose an enjoyable class. One where I know I will not have to stress over tests and homework. Last semester was weight training. This semester as I was browsing I stumbled upon a class titled Geology 270. This class caught my attention right away. I looked at the course description and read it. The thing that stood out the most was that in this class we would study the geology of the eastern Sierra Nevada in one of the most unique ways one could think of, a 3 day field trip. I have never been camping and I thought this would be the best way to do it for the first time. I figured since I would go with teachers and other students it would be both fun and educational. I was not wrong. So, I signed up for the class and signed up my sister for it too. The day of the field trip came quickly.…

    Research Project Climate Change

    There are many questions about global warming, from its causes to its effects, and many people even question whether or not it even exists. Global warming is described as the increase of the average temperature of the Earth caused by increasing concentrations of greenhouse gases produced by human activities, such as deforestation, use of fertilizers, fossil fuel combustion and cement production. According to the global warming theory, the intensification of industrial activities during the twentieth century (based on the fossil fuel combustion such as petrol and coal) increased the concentration of CO2 in the atmosphere.…

    Viviparity In Early Adulthood

    Scientists have done research and consulted with fossil evidence and found a correlation between past climates and the convergent evolutionary move toward viviparity. Viviparity and egg retention served a thermoregulatory process; a way for the squamates to maintain optimal embryo development temperatures because laying the eggs would have left them exposed to unfavourable temperatures. If the embryo of an animal is not developing at the correct temperature their development could take longer, negatively affecting the mother or the embryo could die. Squamates are cold blooded and need to find warmth, for example by bathing in the sun they are able to maintain the temperatures at which their bodies are at. This is but one of the reasons that viviparity evolved. Another reason for the evolution of viviparity is for the protection and safety of the eggs to ensure succession of offspring. By laying eggs as opposed to retaining them they are not only exposed to the elements but also to possible predation. Viviparity allows the mother to save energy in terms of protecting a clutch of eggs from predators; the eggs are also safe from microbial attack, drying out and direct UV…

    Jurassic Period

    Marine life of the Jurassic Period was also highly diversified. The largest marine carnivores were the Plesiosaurs. These carnivorous marine reptiles typically had broad bodies and long necks with four flipper shaped limbs. Ichthyosaurus was a more fish-shaped reptile that was most common in the early Jurassic. Because some fossils have been found with smaller individuals that appear to have been inside the larger ones it is hypothesized that these animals may have been among the first to have internal gestation and bear live young. Among the most beautiful fossils of marine life were left by the spiral shells of the Ammonites.…
