Summary Introduction

To state:

The age and time of Earth when life is thought to have first originated.

Introduction:

Life on Earth was evolved about 3.5 billion years ago, the oxygen was evolved later before the life came into existence and this was possible because of the anaerobic bacteria.

Expert Solution & Answer

Explanation of Solution

Earth is about 4.6 billion years of age. There are some sedimentary rocks that have survived in the destruction during geological processes. These sedimentary rocks in Western Australia and South Africa had some records about the history of Earth. These records in the sedimentary rocks are known as fossils. The evidence of life in early oceans is provided by the stromalites which are the ancient rocks similar to the modern structures.

These modern structures are formed by the microbial groups. By comparing the sedimentary rocks with modern structures, it is proved that life came into existence about 3.5 billion years ago. The evidences show the early atmosphere and oceans contain little or no free oxygen. The accumulation of oxygen in the atmosphere came into existence about 2.4 billion years ago. The presence of oxygen made aerobic respiration possible on Earth.

Conclusion

The evidences from sedimentary rocks are compared with the modern structures that indicate about the life on Earth.

If you transplant trunk neural crest into the cranial neural crest region of a developing embryo, will you see the donor tissue form cartilage? Does the neural crest only give rise to two cells in the developing embryo, and is essential for lamprey to develop their jaw structure? Does a multipotent neural crest cell that is receiving Wnt signals become a Chromaffin cell?
