Science & Technology Q&A for Kids (and others) [February 10, 2023]

Stephen Wolfram answers general questions from his viewers about science and technology as part of an unscripted livestream series, also available on YouTube here: https://wolfr.am/youtube-sw-qa Questions include: Is there a way to digitize DNA sequences and examine them? - ​Is a complete family tree of humanity with billions of connections a realistic possibility? - Is DNA a tree or a semi-lattice? - How likely is it that genetic engineering can create many mammalian species with superhuman intelligence? - Can you speak on epigenetics? Has this effectively resolved the nature vs. nurture question by turning it into an invalid question? - Do viruses play an important part in evolution? - How does the brain distinguish signals coming from different senses? What is the difference between the signals coming from the eye vs. the ear? If everything is ultimately an electrical signal, is this not a difference in degree instead of kind? - What are the implications regarding the ability for the brain to acquire another sense that is unlike the five senses we already have?
