On a cladogram‚ it is shown that some of the early ancestors of the Gray Wolf were a group of carnivores named Creodonts that first walked the northern hemisphere of Earth between 100 and 120 million years ago. About 55 million years ago‚ Creodonts evolved into the Carnassials‚ wolf-like animals that had specialized jaws for ripping and eating meat

warm it up. Not only that‚ but since no sunlight was coming through this huge blanket of ash and gases‚ no plants were able to grow‚ and no plants meant no food for the herbivores and death by starvation‚ and no herbivores meant no food for the carnivores‚ and death by starvation. That‚ and the dramatic shift from a warm climate to an arctic climate was what mainly killed off the dinosaurs. I believe that volcanoes had a role in killing off the dinosaurs indirectly. It was the climate that killed

Stream Study – Ecology and zonation Aim: The aim of this activity is to investigate an aspect of two river ecosystems (Turitea stream and Mangaone stream) and to present a formal report about a presence (or absence) of a pattern. The distributions of invertebrates are compared in both streams for an analysis to be taken out on the distribution of the invertebrates in relation to biotic and abiotic factors. Introduction: The focus of this investigation is to compare the distribution of Mayfly

Misconceptions of the Endangered Sharks “Strong jaws‚ teeth-like scales covering the body‚ gills‚ dorsal fins‚ pectoral fins‚ and a powerful tail‚ along with fantastic camouflage…”(Kraus 91)‚ sharks have been able to remain the top predator of the ocean waters for the past 400 millions years. They belong in the family known as the Chondrichthyes which distinguishes them from other of aquatic life in which they have evolved to have special skeletons made up of cartilage and connective tissues.

The nature of thought is a fascinating topic for conversation; however‚ in order to understand it one must also know the different facets of thinking. The three major aspects to explore when discussing thinking are the sensing process‚ memory‚ and medium. There are also certain perceptual blocks‚ thoughts‚ and personal barriers that may hinder a person’s thought process. The first part of thinking to explore is the sensing process‚ this is very important to the process of thinking. Without

Normally a dolphin will stay in a long-lasting group of 2-40animals called pods‚ but larger groups of hundreds of dolphins have been reported and those are called herds. Dolphins are carnivores that feed on fish‚ squid‚ octopus‚ cuttlefish‚ crabs‚ shrimps‚ and lobsters. Dolphins are food for sharks‚ killer whales‚ humans. Man is the most dangerous predator for the dolphin. Humans will kill dolphins for their meat‚ their fat‚ even for being

“The wolf comeback is due to its listing under the Endangered Spices Act‚ which provided protection from unregulated killing and resulted in increased scientific research along with reintroduction and management programs” (USFW 1). As of May 2011‚ the U.S. government and the U.S. Fish and Wildlife services have officially removed the gray wolf from the endangered species list calling the recovery‚ “one of the most remarkable success stories in the history of conservation.” “There are an estimated

Realistically‚ one detail that is overlooked is the fact that humans are not meant to eat meat‚ but are said to be omnivores anyway. Other animals are naturally meant to be carnivores‚ but humans are not. Whether or not humans decide to stop eating meat is personally up to them‚ but our bodies are not meant to ingest meat. This just goes to show that humans have been so used to eating meat that most of us cannot picture a life
