Evolution - Changing of things over time to benefit the organism in natural selection. Biological evolution happened at the level population ‚ not the individual organism level.

Human Impact And Population The negative human impacts on harbor seals are devastating‚ and there are yet to be any major positive impacts. In the 1900s‚ fur traders would hunt harbor seal pups that were less than four weeks old for their fine coats‚ which were highly valued. This led to a decrease in the harbor seal population. Harbor seals were also hunted by salmon fishermen who saw the seals as competitors for the fish. After a while many harbor seal populations had to abandon traditional haul-out

Our animal is the Bibillius bobois‚ also known as the Bibi Bobois. The phylum our animal comes from is annelisa. What makes our annelid so unique is the way it protects itself‚ keeps predators away‚ reproduces‚ and the way it communicates. The defense mechanisms of the Bobois are especially unique. During the winter the Bobois produces a thick coat of gray slime that will cover its body to create a slimy shell. This slime protects it from cold temperatures by using the Greenhouse Effect to absorb

[pic] Marine biology is the scientific study of organisms in the ocean or other marine or brackish bodies of water. Given that in biology many phyla‚ families and genera have some species that live in the sea and others that live on land‚ marine biology classifies species based on the environment rather than on taxonomy. Marine biology differs from marine ecology as marine ecology is focused on how organisms interact with each other and the environment‚ and biology is the study of the organisms
