According to some geneticists, the common ancestors for humans and gorillas existed around 7 million years ago, and the common ancestors for humans and chimpanzees existed around 5 million years ago. Some geneticists claimed that humans, chimpanzees, and gorillas share at least 90% of their DNA or genome. The shared DNA could be as high as 98% to 99%: “Tiny Genetic Differences between Humans and Other Primates Pervade the Genome” (http://www.scientificamerican.com/article/tiny-genetic-differences-between-humans-and-other-primates-pervade-the-genome/).
This means that a 1% to 10% difference in genome could create vast differences between two or more closely related species. This also explains how much less than 1% of a genetic difference could result in sub-species, cultivars, races or ethnic groups, and breeds. Of course, the cultural Marxists and liberal-guilt peddlers do NOT understand science, or they fanatically believe political science or pseudo-science is more important than genuine science. Thus, they glamorize their fictional superiority regarding extreme egalitarianism while they slander and censor different concepts.
Keep in mind that geneticists still struggle with understanding the genetic code. Sequencing DNA is a lot easier than understanding the DNA code. It’s sort of like copying the text of a book that was written in a foreign language versus understanding the meaning of the foreign book. I could copy the words in correct sequence of an Arabic book, but I would not understand the book at all. I could use an Arabic-American dictionary to tediously define one word at a time, but I would still struggle to understand the sentence structure, paragraph design, grammar, and cultural meanings.
One word is sort of like one gene. Geneticists struggle to understand one gene at a time, especially because each gene could be involved with one or multiple feedback chain-reactions that involve other genetic portions, proteins, and other organic types of simple to complex molecules. These other factors could fundamentally exist inside the organism or come from the organism’s environment (e.g., nature vs. nurture). Thus, two organism with very similar genomes could have significantly different phenotypes.
Here’s an analogy. Two different books could share lots of similarities in their word choices, grammar, sentence pattern, paragraph setup, and overall meaning, but the two books’ specific ideas could still be very different from each other. The first and second novels in the Dune series (by Frank Herbert) are generally similar, but their details are very different. The same could be said about the novels in the Lord of the Rings trilogy, the Condor Trilogy by Jin Yong, etc. To make things even more complex, one person’s interpretation or opinions about a novel could be significantly different from another person’s interpretation of the exact same novel. Similar things could be said about genetic research.
Then there are the moral debates about experimenting with genes and attempts at genetic enhancements. For better or worse, these debates could be easily manipulated by politics and business.
