Science/Archeology

Today in class I watched a one hour movie about fossils and how all life started. I learned a lot from the movie and today i will be blogging about all the things i have learned. All animals on the planet all started from very small and simple organisms and have become more and more complex over time. "Photosynthetic Organisms" photosynthetic organisms are similar to plants but they can survive through more severe climates and can be frozen at the bottom of the ocean and still survive. Photosynthetic Organisms survived through the ice age which was amazing to scientists.

Scientists have many different ways of discovering what life used to be like and life can be found in many different places. They can use what animals look like today to try and help them figure out what they used to look like. A sponge is a form of life and it is a multicellular organism and it has many pores and channels through its body to circulate water. Fossils can be found in very old rocks and one of the places that they were discovered in was Newfoundland which used to be a very volcanic place and many of the early organisms were found there. When the volcanic ashes would turn to rock the prints of the tiny organisms would be left behind and that is how Archeologists have discovered the organisms.

Archeologists found many other micro organisms in a shallow reef in Australia. The organisms that moved came much after the first organisms. Kimmerela was the first mobile organism and could sense were food was so it could feed easier. 2007 is when humans first discovered sexual reproduction in more complex organisms. The earlier organisms couldn't move, had no mouth and had no muscles and have evolved into more complex organisms that are now known as animals.
