Genetic engineering is applied to techniques like DNA cloning in which the steps are: step 1: DNA cutting from the parent source; step 2: DNA cut is pasted into the matrix to be modified; step 3: matrix is introduced to the host cell and step 4, vector DNA is isolated. these are the steps.

Explanation:
Mostly because it was the BIGGEST thing that really happend during said event. The others happend yes but not as majorly as number 1.
Answer:
In humans, genetic variations are caused because humans reproduce by a sexual life cycle which is termed as meiosis. In such a life cycle, the offspring receives half the chromosomes from the mother and half from the father. Crossing over and random assortment of chromosomes are two phenomenons which occur during meiosis. Due to these two phenomenons, genetic variations are caused.
During crossing over, the exchange of DNA segments between the homologous chromosomes takes place which brings about the genetic variations.
