Over a period of 400 million years, animals in the vertebrate category have evolved to a diverse array of life adaptations on earth. Vertebrates represent animals that are most familiar with people and are used for food, adopted as pets and deployed for labor. They include fish, reptiles, birds, amphibians and mammals. The classification system that groups vertebrates according to each of the classes that have been mentioned above utilizes genetics, anatomy, and the evolutionary relationships. Animals are classified starting with the kingdom which is a large body that encompasses animals that have similar characteristics and end up with ...

Increasing temperatures, rising sea levels, erratic rainfall, deadly tsunamis, flooding, wildfires, heat waves, shrinking glaciers, and droughts are some visible highlights of a much debated global problem, i.e., the global warming. The problem is so severe that scientists, environmentalists, geographers, government officials, and various national and international tribunals huddle together time-to-time to embark on a sustainable solution to this issue. Nonetheless, the predicament persists putting everything (human beings, animals, birds, societies, environmental resources) in the soup. This paper discusses the impacts of global warming and the efficacy of solutions that are being implemented at national and global levels. Taking ...

Human overpopulation presents one of the most pressing social, political and environmental issues in the modern world, dramatically aggravating the forces behind environmental pollution, global warming, mass extinction, loss of natural habitats and overexploitation of finite natural resources. According to McKibben (34), fresh water is the most important finite natural resource with no immediate substitute for most uses. Yet, this resource is being depleted at a higher rate than is being replenished. As the human population expands, the amount of fresh water available decreases, which puts the human species at a great danger. It is estimated that by 2030, ...

Scientists, the world over, have a common belief that over 90% of earth’s species have become extinct over the last three billion years that the planet has supported life . It is estimated that there have been at least five mass extinctions spread over millions of years at a time. The latest known mass extinction was towards the end of the Cretaceous period. It is most likely so well known because, the event which occurred over 65 million years ago, caused the end of the dinosaurs. Although in terms of the scale it was smaller than the previous four, ...

Ordovician-Silurian mass extinction is one of the greatest mass extinction in the history. According to statistics, over one hundred families became extinct. This was associated with the movement and fragmentation of the supercontinent. Secondly was as a result of ocean cooling beyond levels the organisms could survive. While the organisms had initially adapted to the warm tropical conditions, the sudden transition to the cold climate was unbearable for most organisms (“Ordovician”,n.d.).. The late Devonian mass extinction is thought to have been warm and dry period. It was characterized by Devonian fish that was the main components of ...
