Fossils can only be formed when mud, silt or tar is in the area to preserve the fossil, If erosion does not occur and allows the fossil to form, and Oxygen and microorganisms cannot decay the bones.
Human Genome Project or HGP was an international and collaborative program, which aimed towards complete mapping, sequencing, and research of the human genome.
<h3 /><h3>What are the primary goals of the Human Genome Project?</h3>
- Human Genome Project was a long, extensive, and collaborative research program initiated in the year 1990 and ended in 2003.
- The aim of the project was to map and sequence the human genome to understand the genetics, hereditary, and other biological studies.
- The primary goal of the HGP was to accurately sequence the 3 billion nucleotide base pairs. The second aim was to identify the genetic sequence in the DNA, which is estimated to be 20,000 to 25,000.
Thus, the primary aim of the HGP was to sequence the 20,000 to 25,000 genes that comprise the human genome.

Secondary succession generally takes place faster in comparison to primary succession as the substrate is already present. In the case of primary succession, there is no soil and it consumes much time to form.
Primary succession takes place in mainly lifeless regions, that is, the regions in which the soil does not possess the tendency of sustaining life as an outcome of various factors.
On the other hand, secondary succession takes place in the regions where a community that previously prevailed have been eradicated and is epitomized by smaller scale turbulence, which do not eradicate all the forms of life and nutrients from the environment.
