He likes to explore things we know a little about, but don’t think about. Carl Zimmer likes to write books about things that he can to investigate. As he says when investigating a topic, the bottom falls out.
When he was considering the topic of heredity, he thought about what’s normally talked about with heredity. We talk about it all the time as we make connections when different generations having similar traits.
In addition to inheriting genes, you inherit the molecules around the genes that control whether they’re turned on or off. These molecules can also change due to experiences. Yet, the evidence and sample size in humans is tiny and cannot be proven completely true.
Unfortunately, science cannot answer this for someone individually. Science can look at averages from lots of people. Genes play a role on average, but we can’t specify this gene in relation of heredity from a parent.
According to Zimmer, scientists are still struggling with this curiosity. You can pinpoint the genes that influence your height, but there are thousands of them that have been linked. It’s the combination of genes, not just what’s on our DNA.
Yes, there are lots of things in life that can influence a person’s personality. Scientists are also looking at hundreds and thousands of people taking personality tests to see if they share the same genes.
According to Bill Nye, there’s a belief or presumption that there’s a connection between family members that they would share. On the show, it would be discovered. Zimmer states it’s because we are adapted to care more about our family.
Zimmer states that yes, it is good to buy the kits, but only if the person is willing to put in the work to understand the results. This includes reading and looking up the results instead of just looking at them.
