knowing the diet of an ancient creature‚ it is reasonable to see how a paleontologist and evolutionist can follow the emergence of the omnivore over the carnivore and herbivore. And the hardness of teeth make it the “best-preserved animal we find in the fossil record for many time periods” (Shubin 61). This clue to these ancient animal’s diets can “give us a good window on how different ways of feeding came about” (Shubin 61). So‚ the shape of the teeth and the general mineral make-up both contribute to

most surprising encounter with the oldest fossil of a hominid that they later called Lucy. Donald Johanson and Tom Gray are pale anthropologists and are very well known for their discovery of Lucy. At the beginning of the book the author writes in the first person illustrating how rare it is to find fossils‚ many who study in this field sometimes have no luck in finding such extraordinary old fossils. Johanson feels “lucky” to have been able to find such fossils that many have been trying to find without

As the title suggests‚ the article "Transitional‚ Old and New" by author Nancy Foner examins the transition of immagrants throughout history and today. Nancy notes immagration creates a unique blending of the culture. The migrant maintains deep rooted ties to the people and culture of their native culture‚ while also adapting to the culture and customs of their new home. America‚ and New York City in particular has been a major host of immagration throughout it’s history. People leave their

because where my house sits at this time it was under water thousands of years ago so there would of been water type dinosaurs. When i go to the beach there are fossils from water dinosaurs in the rocks on the cliff face so that shows that there was dinosaurs in the area. because my house would have been under water there would be fossils like the ones on the beach. Any single person can go to the beach and see rocks that have bones or other fuels on the side of them. I have evidence to support my

As geologists‚ we examine layers of sediment on the Earth’s surface to approximate the dates of past geologic time periods. Ah sediment as you know is material like sand‚ gravel‚ fossil fragments that is transported by natural processes like wind ‚ water flow or the movement of glaciers. So sediment is transported and then deposited and it forms layers on the Earth’s surface over time. We examine these layers to learn about different geologic time periods including when they began and ended. For

Animals like polar bears and penguins‚ can survive because they are endotherms and can keep their body temperature at a certain temperature. According to the research by Rich et al. (2002)‚ almost no ectotherms’ fossils found at polar latitude‚ but dinosaurs’ fossils were found in the Arctic. Conspicuously‚ cold-blooded animals like lizards and crocodilians‚ are not seen at such high latitudes. Ectotherms highly rely on the surrounding temperature to keep active. Although the research mentioned
