Major Features of Vertebrate Evolution: A Palaeozoic and Mesozoic Perspective
The evolutionary path leading to vertebrates was complex and replete with chance. When we consider our own deep history, we seldom think about how steeply the odds have been stacked against us. The world of the distant past, over 3.5 billion years ago, would be unrecognizable to anyone who might be able to travel back to that point in time. The Earth was then a very different place, with no multicellular organisms and a toxic atmosphere composed primarily of nitrogen and carbon dioxide. Oxygen, the lifeblood of our world today, was present only in trace amounts, and the absence of an ozone layer meant constant bombardment by unfiltered UV radiation. The sun was less bright than today but was nevertheless capable of transferring much of its limited output of energy directly to the earth's surface, impacting early life as profoundly as a bombardment of X-rays generated in a laboratory. This particular laboratory experiment would have resulted in rapid mutation rates, with few species surviving for long. Even in these extreme conditions, however, life did hang on, and the survivors must have set the stage for the stunning adaptive radiations that were still to come.

Extraterrestrials in the Catholic Imagination
What do scientists know about the possibility of life outside our solar system? How does Catholic science fiction imagine such worlds? What are the implications for Catholic thought? This collection brings together leading scientists, philosophers, theologians, and science fiction authors in the Catholic tradition to examine these issues. In the first section, Christian scientists detail the latest scientific findings regarding the possibility of life on exoplanets. The second part brings together leading Catholic science fiction authors who describe how “alien” life forms have been prevalent in the Catholic imagination from the Middle Ages right up to the present day. In the final section, Catholic philosophers and theologians examine the implications of discovering intelligent life elsewhere in the universe. Rather than worrying that the discovery of intelligent extraterrestrials might threaten the dignity of humans or their existence, the contributors here maintain that such creatures should be welcomed as fellow creatures of God and potential subjects of divine salvation.
The Evolution Conspiracy, Vol 1
"The Evolution Conspiracy" exposes the faults in evolutionary theories, the half-truths, and the inconsistencies through a secular lens.
An Illustrated Guide to Dinosaur Feeding Biology
This beautifully illustrated exploration of the diversity, anatomy, and evolution of dinosaur feeding adaptations is the first and only in-depth look at this crucial aspect of paleoecology. In An Illustrated Guide to Dinosaur Feeding Biology, experts Ali Nabavizadeh and David B. Weishampel bring dinosaurs to life on the page by exploring and illustrating their feeding adaptations. Whether dinosaurs were carnivorous, herbivorous, or omnivorous, their evolution produced a multitude of specialized adaptations that helped shape their ecologies. Dinosaur skulls show a variety of bone and joint specializations ideal for withstanding stresses and strains induced by high bite forces with strong jaw ...
Amniote Origins
Amniote Origins integrates modern systematic methods with studies of functional and physiological processes, and illustrates how studies of paleobiology can be illuminated by studies of neonatology. For this reason, comparative anatomists and physiologists, functional morphologists, zoologists, and paleontologists will all find this unique volume very useful. Inspired by the prospect of integrating fields that have long been isolated from one another, Amniote Origins provides a thorough and interdisciplinary synthesis of one of the classic transitions of evolutionary history.
