I'm honored to be a guest today over at Mainewords where I've been interviewed by Marcy. I hope you'll stop in and hear all about my latest release, The Marine's Doctor. This is the third and final book in my Recon Marines science fiction trilogy from New Concepts Publishing. I hope you'll visit me there.
As someone with a biology minor and having been a health teacher for more years than I want you to know, I have a strong interest in science. One of the areas I find the most fascinating is the exciting advances in genetics. The cures for so many diseases may rest on our understanding of the human genetic puzzle. Since my fictional Recon Marines are genetically engineered soldiers, I thought I'd share some interesting genetic discoveries.
This first article shares the discovery that we tend to pick friends who share genetic similarities with us. Our friends are usually enough like us to be our fourth cousins. Now most of us don't even know our fourth cousins but researchers say that one percent match is significant. The most common shared gene between friends is the 'smell' gene. We pick friends who like and dislike the same odors as we do.
Some disturbing findings coming out of genetic research is that a mother's diet during pregnancy can alter the fetus' DNA. These permanent changes may influence development throughout life and who knows what else. Another worrisome idea is that the more we learn about genetic differences in people the more certain ridiculous people might use such findings as basis for discrimination. There are already people who have suggested that early genetic testing and intelligence tests could be used to separate children into different schools or courses of study in early childhood. Scary, isn't it?
Have you visited Mainewords today yet? Do you know your fourth cousin? Are you surprised to learn your friends are more similar to you than you expected? Do you find the other two findings as unsettling as I do?
