Answer:
less than 1%
Explanation:
The approximate percentage of the geologic time that humans have existed on the Earth since its origin is less than 1%.
The earth is about 4.6 billion years and much of its history has been without the present of human activities.
- Hominis were the first human to appear on the surface of the earth.
- This was in the Miocene epoch which was about 6 million years ago.
- Compared to the age of the earth, this time lapse is very small and not up to 1%.
- Life first appeared on earth about 3.5billion years.
- Since then evolution has taken its due course to give what we have today.
The DNA technology that is helping in this process is the CRISPR-Cas system.
<h3>What is the CRISPR-Cas system?</h3>
The CRISPR-Cas system is a genome editing tool that has revolutionized genetic and molecular biology.
This genome editing tool can be used to insert specific sequences of DNA into a chromosome and thus generate a new cell expressing of these genes.
In conclusion, The DNA technology referred here is CRISPR-Cas system.
