Extinction and Evolution Ecology helps us understand the importance of mass extinction in evolution‚ and it also helps us understand some of the causes of extinction. Ecological niche is one of the most important concepts to understand. An animal or plant lives in a certain place is active at a particular times‚ and eats certain things; all these factors describe its ecological niche. Our environment is parted into millions of ecological niches‚ each that represents a probable home for life

Task 9: Mass Extinctions Introduction: In this report I will talk to you about the 5 mass extinctions that have happened on earth over the past 434 million years. I will also talk to you about the effects of the current mass extinction. The last things i will show is a list of 10 recently extinct species and 10 endangered species. Number 1: The Ordovician Silurian Extinction This extinction happened about 439 million years ago‚ because of a drop in sea levels as glaciers formed. An ice age has been

Blue Whales: Smarter Than You If you were to step past a worm on the sidewalk would the worm even know what you are or even that you stepped right past it? The idea is to first: prepare your mind to understand what I’m about to share; and second to show that it is very possible for a more intelligent species to be hidden right beneath our noses. If the blue whale has the ability to feel more‚ love more and understand one another better than humans can; one could only wonder what else they can do

groups were relatively unscathed by the Permo-Triassic extinction event‚ although the structures of communities changed. This may have set the scene for the evolution of flowering plants in the Triassic (~200 million years ago)‚ which exploded in the Cretaceous and Tertiary. The latest major group of plants to evolve were the grasses‚ which became important in the mid Tertiary‚ from around 40 million years ago. The grasses‚ as well as many other groups‚ evolved new mechanisms of metabolism to survive the

It is believed Earth may be in the midst of another mass extinction‚ also known as ’The Sixth Mass Extinction ’. This mass extinction is the first for 65 million years since the Cretaceous-Tertiary period. "It ’s the next annihilation of vast numbers of species. It is happening now‚ and we‚ the human race‚ are its cause ’ (Leakey‚ 1995). Every year‚ between 17‚000 and 100‚000 species vanish from our planet‚ which will result in fifty per cent of the Earth ’s species vanishing inside the next 100

climatic conditions impact the evolution of the species? What ultimately resulted in the extinction of the species? The Jurassic Period‚ also known as the Age of Reptiles‚ and is marked from the end of the Triassic period to the beginning of the Cretaceous period; the time frames within this period are broken down into Early‚ Middle and Late Jurassic. There are three main extinction events in the life of the dinosaurs‚ none of which took place during the Jurassic period; however‚ the beginning of

In biology and ecology‚ extinction is the end of an organism or of a group of organisms (taxon)‚ normally a species. The moment of extinction is generally considered to be the death of the last individual of the species‚ although the capacity to breed and recover may have been lost before this point. Because a species’ potential range may be very large‚ determining this moment is difficult‚ and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa‚ where a species

Tyrannosaurus rex means "tyrant lizard king" .It is also called T.Rex abbreviation. The first T. rex was first found by Barnum Brown in 1902. The first T. rex was found in Hell Creek‚ Montana‚ USA‚ North America. Tyrannosaurus rex was a meat-eater about 40 feet (12.4 m) long‚ about 15-20 feet (4.6-6 m) tall‚ and about 5-7 tons in weight. T. rex probably had about 200 bones‚ roughly the same as us (no one knows exactly how many it had‚ since no complete T. Rex Skeletons have been found). About a

study region covers an area of approximately 500 km2. The bottom of Dakhla depression is bordered from the north and north east by steep scarps of the Eocene Limestone plateau‚ but slowly rises to the south where it merges with the plain of Upper Cretaceous Nubian sandstone (Ghadiry et al.‚ 2012). Dakhla Oasis occupies one of a chain of structurally motivated topographic depressions underneath the edge of the Libyan Plateau‚ centered at 25.5°N‚ 29°E. The depression is confined within the 140m contour
