Dr. Geoffrey Simmons focuses on the millions of structures and systems on the Earth that came about all at once, entire...with no preceding links, no subsequent links, no "sideways" links. To illustrate, he surveys examples like... the hummingbird and its circulatory system insects and insect-eating plants the role of the thousands of species of viruses chemical signals and the sensory apparatus that detects them the self-regulating capacity of the Earth's ocean/air/soil system It's clear: Nature containsonly leaps, not links. Only the intelligence and purpose of an all-powerful Designer can explain the intricate creatures, connections, and "coincidences" everywhere. Excellent for students and parents, especially homeschoolers, and for educators who want to present the "full picture."
