Various scientific studies have examined the mechanics of human locomotion. It looks as though mankind was made with an extremely efficient walking "gear." Can evolution be legitimately credited with the unique human leg ingenuity that this efficiency requires, or does the evidence better fit a more intelligent source?

A team of geneticists recently analyzed 6,529 individual genomes, representing 107 different human populations.¹ They found genetic traces of African ancestry in various people groups and estimated the timing of the ancient African/non-African intermarriages.

Fruit flies, the subject of over a century of intense investigation, have not ceased yielding secrets. In a study published in 1980, core fruit fly genes were altered, one by one, and the resulting plethora of dead flies proved that there was no "wiggle room" to add the mutations that evolution would require.¹ Now, researchers have found another way to break the fly.

A piece of oxygen-darkened amber was said to hold a particular arachnid, but it wasn't clearly visible. Scientists made a surprising discovery when a computed tomography scan was able to produce a finely detailed three-dimensional image of a hunting spider. But if the amber is actually 49 million years old, as is claimed, why hadn't it completely darkened long ago?

For many creatures, embryonic development involves the amazing unfolding of a single cell into an animal with billions of cells, each with a specific structure and function. How does a small ball of identical dividing cells know when to start or stop its growth, as well as when or where (not to mention how) to begin differentiating into various types of tissues?
