Extending the Evolutionary Synthesis
The theory of evolution is itself evolving with new findings and changes in the fundamental underlying concepts. It is true that today's synthetic theory, which goes back to Darwin, is persistently successful. However, it offers no convincing explanation to many questions, some examples of which are as follows: What forms of inheritance exist besides genetics; how complex variations, especially evolutionary innovations such as bird feathers and turtle shells, arise; how the environment affects the evolution of species and is changed by them simultaneously; and why the evolution of birds, corals, and human culture is not explainable by natural selection alone. Scientific findings of the last ...

The theories of evolution are themselves evolving with new findings and changes in the fundamental underlying concepts. It is true that today's theory, which goes back to Darwin, is persistently successful. But there remain many unanswered questions.
Electric Airplanes and Drones
Attempts at electric powered flight date to well before the 19th century. Battery weight and low energy output made it impractical until the 1990s, when the advent of lightweight materials, more efficient solar power, improved engines and the Li-Po (lithium polymer) battery opened the skies to a wide variety of electric aircraft. The author describes the diverse designs of modern electric flying machines--from tiny insect-styled drones to stratospheric airships--and explores developing trends, including flying cars and passenger airliners.

Using a fast boat and creative procedures, they establish a smuggling operation with landing points stretching the length of the east coast. Branimir and Danica have a son named Andrei, who is endowed with superior athletic...
