Genetic Science

The woolly mammoth: an iconic extinct species that once roamed the vast arctic tundra during the last ice age. These colossal creatures disappeared thousands of years ago, but now, scientists are working to bring them back.

A massive crossover of cultures and ethnicities often increases genetic variability as children inherit dominant traits from their parents. Each facial feature, skin color, and trait tells a story of people's origins.

Eye contact helps build trust and communication whether in business, friendships or romantic pursuits. Its importance in human socialization means that we're more likely to take note of eye color and wonder, "What is the most common eye color?"

According to the Centers for Disease Control and Prevention, the average height in the United States is 5 feet, 9 inches (1.75 meters) for adult men and 5 feet, 3.5 inches (1.61 meters) for adult women. But some people can reach heights upwards of 7 or 8 feet (2.1 to 2.4 meters)!

Before the widespread use of DNA, establishing the paternity of a child was a tricky business. Ever heard of the oscillophore?

After scientists announced the first draft of the human genome, people began to wonder how our new understanding of DNA would change life. Several research institutes stated the accomplishment would revolutionize science and modern medicine -- but how, exactly?

What's more fun than looking at pictures of DNA and celebrities? Check out Dolly, dimples and dominant and recessive traits in this fun gallery charting how genetics play out in humans (and a few animals).

How can children from the same parents look so different? I mean, why don't all kids from the same parents look exactly alike, since the parents just have one set of chromosomes each and they don't change?

This week, a group of London-based scientists requested official permission to begin a three-year study involving stem cells derived from human-cow hybrids.

Hereditary illnesses are passed down from parents to their children like gene traits, and children might inherit a disease even though their parents never suffered from its symptoms. Learn about hereditary illnesses.

Given the choice, would you rather have been born with a different eye color, hair color or skin tone? Of course, you didn't have these options, but could you have them for your own children?

The CBS drama "CSI: Crime Scene Investigation" routinely uses cutting-edge technology to solve crimes, including collecting and analyzing DNA evidence. But catching a criminal using DNA evidence is not quite as easy as "CSI" makes it seem.

It's a chicken-or-egg situation: What came first? Perplexed people need wonder no longer, as we've sussed out the answer to this ancient riddle.

Cloning is the process of making a genetically identical organism through nonsexual means. In this article, we will examine how cloning works and look at possible uses of this technology.

What is the difference between a hardwood and a softwood? How hard does a tree have to be to be considered hardwood?

With movie titles like "Attack of the Clones" and "The Clone Wars," it's no wonder human cloning makes us anxious. As scientists make startling discoveries cloning animals, are humans next?

Doctors always want your blood, but one day, a health care professional may ask you to open up and say, "Ptooey!" Why? Your spit holds a mother lode of biological information.

Can humans live forever? No, but thanks to the discovery of the Hayflick limit, we know that cells can conceivably divide forever without dying.

Much like Noah, researchers are stockpiling the genes of Earth's living creatures, loading them into state-of-the art facilities and freezing them. Are scientists saving them for a rainy day?

Neanderthals and humans coexisted for thousands of years, but the relationship between the two species was always a bit dysfunctional. Could we get reacquainted with our evolutionary peers?

Wouldn't it be nice to grow crops that grew 50 percent more than current varieties? How about a strain of vegetables that were safe from insects without using pesticides? Agricultural biotechnology can do that.
