The Legacy of Lucy: Tracing Human Origins

It all began with a woman–Lucy, the ancient ancestor whose discovery reshaped our entire understanding of evolution. While she might’ve not been the first hominin to walk the Earth, her remarkably well preserved remains provided the first ground breaking evidence of early bipedalism, confirming that our ancestors walked upright long before they developed large brains. Unearthed in 1974 in Ethiopia’s Afar region, she was named after “Lucy in the Sky with Diamonds” by The Beatles, which played in the background as scientists celebrated their find. Lucy’s skeleton became a key piece in the puzzle of human evolution, cementing Africa’s role as the cradle of humankind and sparking a wave of research that continues to this day. 

Lucy’s skeleton, which was about 40% complete, revealed critical information about early hominins. Her anatomical structure confirmed that Australopithecus afarensis was fully bipedal, meaning that walking on two legs evolved before larger brain development occurred. This challenged earlier theories that intelligence was the first major evolutionary shift. Instead, Lucy demonstrated that bipedalism allowed early hominins to free their hands for tool use, food gathering, and social interactions. 

Her discovery also arrived at a crucial turning point in paleoanthropology. “Lucy’s discovery came at a very important moment in paleoanthropology, when there was beginning to be greater public awareness that Africa is the cradle of humankind,” said Dr. Ebeth Sawchuk, Associate Curator of Human Evolution, in A Groundbreaking Discovery Turns 50: Celebrating the Story of Lucy. Before Lucy, many still clung to outdated ideas that human evolution had stronger roots in other parts of the world. However, as highlighted by the Institute of Human Origins at Arizona State University, Lucy provided irrefutable fossil evidence that early human ancestors originated in Africa, reinforcing the continent’s role in our evolutionary story.

Lucy’s discovery not only revolutionized our understanding of human evolution but also played a pivotal role in advancing research on women’s biology. Her remarkably preserved skeleton provided crucial insights into the anatomical structure of early hominins, including key differences in pelvic shape and locomotion that shed light on childbirth and reproductive adaptations in human ancestors. By studying Lucy and other female hominin fossils, scientists have gained a deeper understanding of how biological and evolutionary pressures shaped the development of female physiology, influencing everything from bipedalism to maternal health in modern humans.

Lucy’s influence reaches far beyond the realm of science—her discovery has shaped anthropology, philosophy, and even our understanding of what it means to be human. She stands as a reminder to us that all humans are linked by a lineage that stretches back millions of years. From the African plains where she once walked to the intricate societies we inhabit today. 

Today, cutting-edge technologies like DNA analysis, artificial intelligence, and 3D fossil reconstruction are shedding new light on our origins. As ongoing discoveries continue to refine our understanding of human evolution, they also highlight the crucial role of women in shaping our species’ history—from the reproductive adaptations of early hominins to the impact of maternal health on survival. While research continues to evolve, one thing remains certain—Lucy’s story was only the beginning.

U.S. Withdrawal from The World Health Organization: Everything You Need to Know 

Sanya Talwar
February 2025

On January 20th, President Trump signed an executive order that officially declared the beginning of the United States withdrawal from the World Health Organization (WHO). This decision has marked a significant shift in global health governance. 

Background on WHO 

WHO, established in 1948, is a specialized agency of the United Nations responsible for improving international public health. It plays a crucial role in coordinating responses to global health crises, setting health standards, and providing medical assistance to areas in need.¹ The United States has been a key member and financial contributor to WHO since its inception post-WW2, underscoring its commitment to global health initiatives. ² 

U.S. decision to withdraw from WHO and its implications 

The U.S. government, under President Trump’s administration, announced its intention to withdraw from WHO on July 6th, 2020, citing concerns over the organization’s handling of the COVID-19 pandemic.³ Key points of contention included perceived delays in declaring a public health emergency, alleged lack of transparency from China, and concerns over WHO’s independence from political influence. The decision was framed as part of a broader reassessment of U.S. engagement with international organizations. ⁴ 

The withdrawal of the United States from WHO has far-reaching implications for global health governance. As the largest financial contributor, the U.S. provided approximately 15% of WHO’s $4.8 billion 2020-2021 budget, including $893 million in voluntary funds for specific programs.⁵ Immediate termination of these payments risked disrupting polio eradication campaigns, HIV/AIDS programs, and emergency response capacities in low-income nations. ⁶ 

Moreover, the U.S. withdrawal may undermine the collective response to global health challenges. WHO relies on international cooperation to address issues such as pandemics, vaccine distribution, and health equity. The absence of the United States could weaken the organization’s authority and effectiveness, potentially leading to fragmented and less coordinated global health efforts.

Potential consequences 

1. Impact on COVID-19 Response: WHO’s ability to coordinate the global response to Covid-19 may be compromised. The U.S. withdrawal could lead to reduced funding for vaccine distribution, research, and support to healthcare systems in vulnerable regions of the world. For example, the WHO-led COVAX initiative, aimed at equitable COVID-19 vaccine distribution, faced uncertainty without U.S. participation, potentially exacerbating disparities between high and low-income countries. ⁷ 

2. Global health security: The base of the United States may create a vacuum in global health leadership, potentially allowing other nations to exert greater influence over WHO’s agenda. This shift could impact the organization’s priorities and decision-making process. 

3. Health Equity: WHO’s efforts to address health disparities and promote universal health disparities and promote universal health coverage may be hindered. The U.S. withdrawal could result in reduced funding for programs aimed at improving health outcomes in low and middle-income communities. 

4. International Relations: The decision to withdraw from WHO may strain U.S. relations with other nations and international organizations. It could be perceived as a retreat from multilateralism, potentially weakening the United States’ position in global health diplomacy. 

The U.S. withdrawal from WHO represents a significant but detrimental development in global health governance. While the decision reflects concern over the organization’s handling of the COVID-19 pandemic, it also realizes important questions about the future of international cooperation in addressing global health challenges. The implications of this withdrawal are profound, affecting not only WHO’s operational capacity but also the broader landscape of global health security and equity.
