Most other animals have this functioning DNA but at some point in our history, a mutation disbled the gene - whilst leaving behind its remnants as junk DNA.
Besides the tendency variation in each point, the strain mutation appears except the sample of soft inclusion, based on which the concept of strain nucleation is put forward.
除软包体型试样外,各点应变除趋势性变化外,都出现应变突变。据此提出应变成核概念。
