We know Homo sapiens started in Africa, but we're uncertain about how they spread. Limited fossils and data have hindered our understanding. I'll discuss popular theories about our origins and how recent genetic data from Khoe-San people in southern Africa sheds light on this. Our research suggests a complex history, with population structures dating back to about 120,000-135,000 years ago. Early populations had connections, or gene flow, for hundreds of thousands of years. These "weakly...

The human body is made up of billions of cells. These cells are the basic building blocks of life, and they work together to form tissues, organs, and systems that enable our body to function and carry out various activities. Each cell has its own specific function and role in maintaining the overall health and functionality of the body. From the skin to the brain, muscles to blood, and everything in between, these countless cells collaborate harmoniously to keep us alive and well, but how do...

Africa is thought to be the ancestral homeland of all modern human populations within the past 300,000 years. It is also a region of tremendous cultural, linguistic, climatic, and genetic diversity. Despite the important role that African populations have played in human history, they remain one of the most underrepresented groups in human genomics studies. A comprehensive knowledge of patterns of variation in African genomes is critical for a deeper understanding of human genomic diversity,...

The first Neandertal DNA was recovered 25 years ago, and since then, ancient DNA has provided many surprising insights into human evolutionary history. Among these are the discoveries of the multiple admixture events among late Pleistocene humans and the remnants of archaic DNA in our own genomes. How does ancient DNA research contribute to the future of anthropogeny? In this talk, I will reflect on the findings of last quarter century of ancient DNA research about archaic humans and their...

The discovery and resolution of genetic variation is critical to understanding disease and evolution. Our most recent work sequences diverse human and nonhuman primate genomes using both ultra-long and high-fidelity long-read sequencing technologies. Advances in this area have made possible the first telomere-to-telomere assemblies of the human genome and much more complete chimp, gorilla and orangutan genomes providing new biological insights into regions typically excluded from human...

Our bodies are dynamic ecosystems housing trillions of microbes that, while invisible to the naked eye, play a critical role in shaping human health. Scientists are just beginning to understand the superpowers the microbiome holds. In this program Marina Sirota, Ph.D., explains how to use artificial intelligence to study the microbiome and better understand health and disease across the lifespan.

We are experiencing an accelerated rate of loss of species due to human activities. This anthropogenic phenomenon extends beyond extinction. It encompasses an expanded loss of biodiversity as the genetic diversity of species diminish, reducing gene pools to “gene puddles.” We know details of species extinctions events from the fossil record, historical record, and from ancient DNA studies, and that historical processes shape extinction risk. Habitat loss and changing eco-environmental...

Amazing new technologies in developmental biology and genetics research are allowing scientists to begin to answer long standing questions such as – how does a single fertilized egg cell transform into a complex animal? Why does the embryo of a marine organism like a sea slug develop differently from that of a sea urchin? Join Scripps Developmental Biologist Deirdre Lyons as she describes how she and her colleagues are pushing the limits of our knowledge to understand these intriguing...

To Sheng-Ying Pao, the power of reframing CRISPR lies in what is absolutely ordinary: paper. In CRISPaper, Pao revisited a cultural past in the ancient art of papermaking. Over thousands of years, farmers painstakingly converted the wild rice plant into a staple crop. Today, researchers are using CRISPR to change genes to optimize grain yield. However, rice is more than food. In ancient China, it was used to make paper. Pao took rice stalks from plants edited with CRISPR and ground the...
