In the past the global climate has changed many different times, usually in a similar pattern. After every extinction in time the worlds climate falls to an all time low, then followed by a dramatic increase in life and temperature. El Niño is an irregularly occurring and complex series of climatic changes affecting the equatorial Pacific region. It originated through the dramatic climate changes over the past million years. A lesson learned through el Niño is the dramatic climate changes we make that cause a more dramatic el niño. Life could of originated along deep sea vents because they produce essential nutrients and heat and is a habitat for animals. Banded iron and stromatolite rocks tell us that photosynthetic organisms were making oxygen, but it reacted with the iron dissolved in seawater to form iron oxide minerals on the ocean floor, creating banded iron formations, and cyanobacteria was the main life on the planet at the …show more content…
The wall has two sides, one that represents the plant, fungi, and bacteria life all the back to the simplest of forms. The other side is filled with all the different types of animals that live on this earth. Another great exhibit in the museum is about all the information on extinct species and endangered species. The greatest extinction in history was the 3rd cultural extinction, this was the end of the Permian-Triassic period, it killed 57% of all families, 83% of all genera and 90% to 96% of all species. The latest extinction is still going on today, the extinctions have occurred at over 1000 times the normal extinction rate since 1900, This mass extinction is considered a result of human activity. Another great exhibit is the Milstein Hall of Ocean Life, this exhibit can tell us a lot of information on marine life and its environment. One display is the trees that show the different species and their kingdoms. This exhibit shows the different ecosystems of the ocean, like the arctic, coral reef, deep sea, kelp forest mangrove, rocky shore, and sandy shore ecosystems. The exhibit talks about the ordovician seas and the animals that lived in it. The Ordovician is best known for its diverse marine invertebrates, including graptolites, trilobites, brachiopods, and the conodonts. A typical marine community consisted
