An exploration of how acceptance of panspermia will soon change history Mainstream consensus is that life arose on Earth spontaneously out of “primordial soup.” Yet this theory, as well as the Darwinian “survival of the fittest” concept as it relates to major steps in evolution, has no scientific basis or proof. Where, then, did life come from? As the authors show, with conclusive scientific evidence, life came from space--a concept known as “panspermia.” We humans, and all other life on Earth, evolved over millennia in response to viruses that arrived via comets, and we continue to do so. Exploring the philosophical, psychological, cultural, and environmental ramifications of the acceptance of panspermia, the authors show how the shift will be on par with the Copernican Revolution--when it was finally accepted that the Earth was not the center of the Universe. Explaining the origins of the panspermia theory in the work of the late Sir Fred Hoyle, the authors reveal the vast body of evidence that has accumulated over the past 4 decades in favor of the cosmic origins of life, including viral inserts found in DNA that have shaped our human genome over millions of years. They show how the tiniest of viruses, microscopic animals (tardigrades), and even seeds have been found to be natural cosmonauts. The authors also show how space-borne viruses play a crucial role in the positive evolution of life and that our entire existence on this planet is contingent on the continuing ingress of cosmic viruses. Revealing how panspermia offers answers to some of humanity’s longstanding questions about the origins of life, the authors discuss the impact this shift in understanding will have on our relationship with the Earth and on culture, history, and religion. And perhaps the most dramatic ramification of all is that acceptance of panspermia means acceptance that Earth is not unique--that other life-filled planets exist and intelligent life is common in the Universe. Not only did we come from space, but we are not alone.

Since slavery, Black women have struggled to liberate themselves from racism and sexism. Yet despite these hurdles and under the most difficult circumstances, they managed to achieve greatness. TRAILBLAZERS shines a light on these their accomplishments, which often led to widespread cultural change. TRAILBLAZERS is a six-volume series that examines the lives and careers of over four hundred brilliant women from the eighteenth century to the present who blazed uncharted paths in every conceivable way. Each TRAILBLAZERS volume is organized into several sections. Along with biographical information and powerful photographs, David provides a historical timeline for each section—written from the viewpoint of Black women—that maps out the significance of the featured women that follow. Volume 1 features an assortment of sixty-five activists, dancers, and athletes. We learn about the significance of activists like Ella Baker, Pauli Murray, Rosina Tucker, and Clara Day, who represent the hundreds of unnamed women who participated in the civil rights and labor movements. We re-discover dancers Jeni Legon and Margot Webb, who are honored alongside dance legends Josephine Baker, Katherine Dunham, Janet Collins, and a new generation of dancers including Misty Copeland, Dormeshia Sumbry-Edwards, and choreographers like Camille A. Brown, and Cynthia Oliver. And then there are the Black women athletes who disrupted the world of sports, from the nearly forgotten tennis champion Ora Washington and Alice Coachman—the first to compete and win in the Olympics—to Simone Biles, the most decorated gymnast in Olympic history. Throughout the series, as David re-introduces many of these women into the public sphere, they are not always in predictable ways. For example, Debbie Allen makes a brief appearance in this volume, not for her acting or as a director, but rather as the dancer she initially trained to be, reminding us that Black women are multifaceted, multitalented, and complex. What binds these women together is that as they struggled on the front lines, they shook up the status quo of Black people in America. Throughout the volume, David also challenges the socially conditioned assumptions, stereotypes, and false binaries that denigrate Black women’s bodies particularly in dance and sports, including the barriers they face in how they wear their hair. In this regard, David addresses the totality of Black womanhood: physically, culturally, and politically. With painstaking research, David has created an affordable, visually rich, and accessible reference book. From the foremothers who blazed trails and broke barriers, to the women who follow in their footsteps, TRAILBLAZERS offers powerful and inspiring role models for women and girls from all cultural backgrounds and for the intellectually curious. TRAILBLAZERS is a clarion call for recognition of the transformative work Black women have done and continue to do. Written in accessible prose that contains personal reflections for a broad audience, TRAILBLAZERS also serves as a vital reference guide for use in schools and libraries.
