The mammalian line of descent reaches back to over 300 million years. The ancient relatives of mammals were extremely different in terms of appearance from living mammals, and are often mistaken for reptiles (for example dinosaurs). In reality though, these relatives of mammals, called synapsids, are more like mammals than reptiles. Synapsids are often described as “mammal-like reptiles” because they show both reptilian and mammalian traits. They lived right before the Mesozoic Era, during the Permian

Precambrian Era The Precambrian era laster 4600-541 million years ago. During this time, there were no plant life on the planet. Most of the things that were on the planet were rocks. The most common type of rock was Isua greenstone. Most rocks have been eroded away, subducted, or metamorphosed. During this time, the atmospheres and oceans were formed, plate tectonics began to build up continental masses. The air during this time was mostly made up of water vapor, carbon dioxide, and nitrogen.

From the presentation the 6th mass extinction: 1. Describe what biodiversity is and why biodiversity is so important. Biodiversity is the variety of spices within plants and animals in the environment, it is an indicator of ecosystem health. The importance of biodiversity: Biodiversity provides humans with food and materials (like wood) that benefiting the economy. Biodiversity performs a variety of ecological services: from absorbing chemicals to cleaning water and providing oxygen. Some types

The carboniferous period lasted from about 359.2 to 299 million years ago, during the Paleozoic era. The name “carboniferous” came from the large amounts of carbon-bearing coal that was formed during the period. Several major biological, geological, and climatic events occurred at this time. The amniote egg allowed further exploitation for certain tetrapods. It enabled ancestors of birds, mammals, and reptiles to lay their eggs on land without fear of being dehydrated. The carboniferous

In modern popular culture, Dunkleosteus is by far the best known and most often represented of the early placoderm carnivores. However Dunkleosteus actually sat within the Dinichthys genus for a long time as the species Dinichthys terrelli. It was not until the large numbers of Dinichthys remains were re-studied that it was realised that a large number of the Dinichthys fossils actually represented different genera, not species. The result was that many of these remains were split to form new genera

One topic that biologists are most interested in is the patterns of life on Earth. One of the ultimate questions for a biologist to answer is how do new species arise, and for what reasons do they disappear? Biologists all over the world are searching for answers regarding the rapidly diminishing amounts, and in some cases, extinction of many of Earth’s species. Scientists are coming out with results that show current anthropogenic climate change is the main culprit for Earth’s continuing loss of

The early Devonian period is largely considered to be a world of a diverse array of lobe-finned fish, including lungfish, coelacanths, and bony fish. Over the course of time, vertebrates made evolutionary strides with provided them with the ability to travel on land. Coelacanths developed a single boned shoulder girdle, lungfish developed paired fins, and sauripterus developed the major structures on the arm (humerus, radius, and ulna). As these developments progressed and environmental pressures

“In pushing other species to extinction, humanity is busy sawing off the limb on which it perches” (The Sixth Extinction, 268). This powerful quote, by Stanford ecologist Paul Ehrlich, accurately sums up the main message conveyed in Elizabeth Kolbert’s most recent and most successful book, The Sixth Extinction: An Unnatural History. Elizabeth Kolbert is an experienced journalist and author who is currently working as a “staff writer at The New Yorker.” While Elizabeth Kolbert has written on a variety

Coal was formed during the Carboniferous Period, which was between 360- 290 million years ago. All of the coal originated from plant fossils. Around 400 million years ago plants once grew around fresh water swamps. As they eventually died, the plants fell and accumulate in the water. Many layers of sediments, mud and sand compressed the plants and allowed no oxygen, which results in no decomposition. Over time the layers get built up resulting in immense pressure and heat transforming each layer

As, the director, of the natural history museum I have created a display dedicated to the Paleozoic time period. In order to boost the attendance, I have designed an interactive set of exhibits and displays for the Paleozoic Era. Guest will enter the museum together in a main room once everyone was seated you would turn down the lights and with a 3 - D show the beginning of the era which was the breakup of one supercontinent and the formation of another. A speaker will explain how the Paleozoic
