Some Information’s:
Extinct species are species when it no longer exists.
Species become extinct when there is
no more reproduction and
its population drops to zero.
There are different time span during which organisms evolved and it’s divided into 4 different eras- which is the Pre- Cambrian, Paleozoic, Mesozoic, and Cenozoic. Each era is further divided into periods (Epochs) and the different number of years included. Likewise the eras are characterized by the kind of multicellular life that appeared. It shows this time frame and the characteristics of life forms that evolved during each era. An era is a large division of time used by geologist to divide Earth’s history.
The Earth has a “clock” to inform us what and when things happened during those years. The Earth’s past history, with the help of a record in the rocks, is called geologic time scale. This timetable of the Earth’s history and was constructed by the geologists. How did they come up with this “clock”? More than 100 years ago, researchers noticed that some layers often appeared in the same vertical order wherever they were found. It is the position of the layers relative to each other that determines their age. Lower layers are older than upper layers, provided that the layers have not been disturbed since they were formed. Relative dating is a technique used by scientists to determine the age of fossils relative with other fossils in various layer of rock.
Reaction:
In my simple research I realized that we have different life and time span, also that we have layer or different stages in life. I would like to share a simple quotation from H. G. Wells “The past is but the beginning of the beginning, and all that is and has been is but the twilight of the dawn. A day will come when beings who are now latent in our thoughts and hidden in our lions… shall laugh and reach out their hands amid the stars”. I realized that past is past and present is present hat we should be focused in what were doing and in that past experience should be corrected. With that you should face it with light, also there will come a time that you would buried in our hearts and soul. Just face your latent thoughts with a midst of other people guiding you.
