It is similar in some ways to genetic algorithms or evolutionary algorithms, but requires less computational cost and generally only a few lines of code.

这种算法在有些地方与遗传算法或竞争算法相类似，但是计算量更小，而且源程序更简单。

The literature on similarities and differences between ES cells and iPS cells, he said, is quite controversial and scientists still do not know whether differences between different iPS cell lines are just due to genetic differences between the adult cell lines that were used for reprogramming or whether genetic changes occurred during reprogramming.

At the same time, many prominent geneticists, including those who mapped the human genome, have publicly said that genetic differences, especially those that occur along racial lines, don't amount to much.

And to understand different diseases, they'll need to create lines from human embryos that suffer from a genetic disorder.
