Lucy is one of the most famous fossils of all time. The discovery of this species had a major impact on the science of human origins and evolution. Why? What was that impact? The symposium speakers—each a prominent scientist in their field—will address this question and specifically discuss the discovery’s impact through time, starting with the first few years after the discovery, the lasting impact, and the state of the art in that research area today. We're celebrating the 50th anniversary of the discovery of the fossil skeleton “Lucy” with the aim of reigniting a global interest in how we “became human” and promoting the importance of connecting our human past to the global future on the planet.

The discovery of a 3.2-million-year-old hominin skeleton named Lucy revolutionized human evolutionary studies. Her Linnean classification as Australopithecus afarensis sparked debates on taxonomy, highlighting the complexity of interpreting fossil evidence and shaping our understanding of hominin evolution. Lucy's systematics provide insights into the challenges of classifying early hominins, emphasizing how interpretations evolve with new evidence and knowledge. Comparing fossils with living ape taxa and extinct species helps infer evolutionary relationships, while considering temporal variation adds depth to our understanding. Lucy's case illustrates the ongoing debate on species classification in paleoanthropology and the critical role of evidence in shaping taxonomic hypotheses.

How much do we really know about the quantum nature of space and time, the origins of the universe itself, and its most mysterious phenomena - black holes? In this program, Clifford Johnson, professor of physics at UC Santa Barbara, explains why understanding the laws of physics helps explain how the world around us works, and can fuel our imaginations to dream, invent, and create. Johnson works to engage the general public with scientific ideas, through many media outlets, including the entertainment industry. He has been a science advisor for many movies and TV shows.

Catherine Yeung, Pharm.D., Ph.D., M.P.H., discusses groundbreaking advancements in kidney-on-a-chip technology, emphasizing its potential to revolutionize human health. She delves into the role of environmental toxins, such as okra toxin A, microplastics, and plasticizers, in contributing to chronic kidney disease, particularly in regions with specific dietary practices. Yeung also addresses the challenges of replicating adult kidney cells from stem cells, which often retain a fetal phenotype, and underscores the value of stem cell-derived models for genetic manipulation and disease research. Additionally, she highlights the increased risk of kidney stones in astronauts post-spaceflight and the broader implications of organ-on-chip technology for studying therapies and diseases.
