As stratum is analyzed on the lower levels‚ we can see fossilize dinosaur bones‚ while on successive levels we see Neanderthal bones.

Understand the concept of a biosphere and Earth System Science and that the biosphere has evolved over time. -Mass extinction: a crisis that affects life right across the planet from the deepest oceans to the highest mountains -Biosphere: all life on Earth is a part of the biosphere‚ a thin layer of life that exists on the surface of the planet and that interacts with the hydrosphere (oceans‚ lakes‚ and rivers)‚ the atmosphere‚ and the lithosphere

Evolutionary Concepts Defining Speciation: BSC and Recognition concept Species are produced by individual speciation events‚ so a single species concept can’t be defining all species. Hugh Paterson’s ideas are significant in understanding evolution. Paterson argues that speciation is not an adaptive process‚ but is a result of the adaptation of intricate bonding mechanisms to a new environment (Paterson). The conceptual basis of his research is the Recognition Concept of Species. He argues that

In the late century‚ extinction becomes common topic in our daily discussion and debates. An average of 27‚000 species is currently extinct each year and there is a possibility of 22% of extinction in the overall species if action is not taken. Animal extinction is due to human immorality and irresponsible behavior just for their own benefits. Since the year 1600‚ a total of 83 mammals species are known to have become extinct. Wildlife population depleted the trade in live animals‚ damaged habitats

The first period of metatherian diversification occurred in the late Cretaceous. The K-T mass extinction created an ecological void in which mammalian radiation occurred in the Palaeocene. With South America isolated from North America throughout the Tertiary‚ there was the second great period of metatherian
