Recently, Bill and Melinda Gates reached out to collaborate on a video project inspired by their annual letter, which outlines their philanthropic goals. A key focus for 2017 is maternal and infant health, aiming to support initiatives that ensure women remain healthy during pregnancy, childbirth, and the early years of their child’s life. The Gates Foundation has been instrumental in elevating global health and education topics, and this collaboration is an exciting opportunity to delve deeper into these critical issues.
Dr. Robert Martin, a biological anthropologist, has dedicated his career to studying hominid evolution, particularly the physical aspects of human reproduction and childbirth. His research highlights the logistical challenges of human childbirth, which involve navigating a baby’s head and shoulders through a pelvic opening of similar size. This complexity is a result of evolutionary changes due to bipedal locomotion, which altered the pelvic shape. Human babies also have longer gestation periods and larger heads, leading to potential complications during childbirth.
Dr. Martin’s studies suggest that these challenges began with the genus Homo around two million years ago, indicating that women may have relied on assistance during childbirth for millennia. This reliance on help, possibly from midwives, underscores the need for support during the birthing process.
Examining the fossil record provides insights into the evolution of childbirth practices. For instance, the pelvis of Lucy, an Australopithecus from Ethiopia, offers clues about the size of the birth canal and the likely size of a baby’s head at that time. By the time of Homo erectus, around 1.5 million years ago, childbirth had become more challenging, likely necessitating midwifery assistance.
Despite the historical undervaluation of midwives, studies show that women often experience better psychological outcomes when working with midwives compared to hospital births. For example, research in the Netherlands found that midwife-attended births were significantly shorter than those attended by obstetricians.
Globally, approximately 300,000 women die annually from pregnancy-related issues, many of which are preventable with access to basic healthcare. Improving healthcare and nutrition access is crucial for reducing child mortality rates. Medical advancements have significantly reduced birth-related mortality in industrialized countries, yet challenges remain, particularly in developing regions like Africa.
In the United States, maternal mortality rates are concerning, with Texas experiencing a doubling of rates after 2011 due to the closure of prenatal clinics. Despite these challenges, global improvements in maternal and infant care are evident, with a significant decrease in child mortality rates over the past century.
Access to prenatal care has been pivotal in improving maternal and infant health outcomes. However, misconceptions about cesarean births as an easy solution persist. The World Health Organization recommends cesarean births in only 10-15% of cases, yet the rate in the United States is currently one in three. This trend poses risks and underscores the need for careful consideration of childbirth methods.
The future of maternal and infant health hinges on equitable access to healthcare and education. With the right resources, we can continue to save millions of lives and improve health outcomes worldwide.
This exploration of maternal and infant health is supported by the Bill and Melinda Gates Foundation and the Field Museum in Chicago, Illinois.
Conduct a research project on the evolutionary challenges of human childbirth. Focus on how bipedal locomotion and evolutionary changes have impacted childbirth. Prepare a presentation to share your findings with the class, highlighting key insights from Dr. Robert Martin’s studies.
Analyze case studies of midwifery practices across different cultures and historical periods. Compare these practices with modern obstetric methods. Discuss in a group setting how midwifery has contributed to maternal and infant health outcomes, referencing the Netherlands study mentioned in the article.
Participate in a debate on the pros and cons of cesarean births. Use data from the World Health Organization and the article to support your arguments. Discuss the implications of high cesarean rates in the United States and explore alternative childbirth methods.
Organize a workshop to explore global initiatives aimed at improving maternal health. Investigate the role of organizations like the Gates Foundation in reducing maternal mortality. Develop a proposal for a new initiative that addresses current challenges in maternal health, particularly in developing regions.
Create an interactive map displaying maternal mortality rates worldwide. Use data visualization tools to highlight regions with high mortality rates and identify factors contributing to these statistics. Present your map to the class and discuss potential solutions to improve maternal health globally.

Hey! A few weeks ago, Bill and Melinda Gates reached out to us about creating a collaborative video based on a theme in their annual letter. This letter outlines their philanthropic goals for the upcoming months. One of their priorities for 2017 focuses on maternal and infant health. They aim to support initiatives that ensure women remain healthy throughout pregnancy, childbirth, and in the early years of their child’s life. We’ve included a link in the description for you to check it out yourself. The Gates have done significant work to elevate important topics around global health and education, and I’m really excited to collaborate with them on this project, so be sure to take a look!
You might remember Dr. Robert Martin, who has appeared in episodes like “Breast Episode Ever” and “Why Did King Tut Have a Flat Head?” He is a biological anthropologist who has dedicated his career to researching various aspects of hominid evolution. A significant part of his work focuses on the physical aspects of human reproduction and childbirth, as well as how trends and practices in childbirth have changed over time. This made me reflect on the logistical challenges of human childbirth that I mentioned in the King Tut video.
I had never fully appreciated the logistical constraints of human childbirth before. The process involves navigating a grapefruit-sized head and shoulders through an opening of roughly the same size, while also making a turn to get around the tailbone. When comparing the pelvic size and shape to that of our closest great ape relatives, ours is disproportionately smaller and more obtuse. This is due to the evolution of bipedal locomotion, which altered the shape of the pelvic opening. Additionally, human babies have a longer gestation period, larger body sizes, and larger heads, which leads to complications during childbirth. In a recent blog post, Dr. Martin noted that the challenges of childbirth began to emerge with the genus Homo around two million years ago. This suggests that women may have been relying on assistance during childbirth for as long as two million years!
I began to wonder how our difficulties with childbirth have impacted mortality rates for both mothers and infants. Save the Children estimates that one million babies die on their birth day every year. So, why does this happen, and are things improving? Spoiler alert: things are actually getting better, and I spoke with Dr. Martin to find out more.
This is what a baby’s head looks like at birth, and it must fit through the pelvis. The baby enters with its head facing sideways and then turns 90 degrees to point backwards as it moves through the pelvis. This challenging passage is a result of the trade-off between the adaptation of the pelvis for upright walking and the size of the brain. This indicates the need for some form of assistance during childbirth. While we don’t know exactly when this began, we can trace the process through the fossil record. My guess is that midwives started being needed about a million years ago.
EG: You mentioned earlier that we have a great record of how humans have evolved over time, including birthing practices. Can you share some examples from the fossil record?
RM: This here is one side of the pelvis of Lucy, the famous Australopithecus from Ethiopia. By mirroring the pelvis, we can estimate the size of the birth canal.
EG: Great.
RM: We can also calculate the likely size of the baby’s head. By the time we reach Homo erectus, around 1.5 million years ago, we can infer that childbirth was becoming more difficult. They likely experienced slower births and may have already needed midwives at that stage. Midwives have often been undervalued. There has been a trend towards the medicalization of birth and a push for hospital births. Studies have shown that women often fare better psychologically when working with midwives rather than in the impersonal environment of a hospital. For instance, a study in the Netherlands found that births attended by midwives took significantly less time than those attended by obstetricians.
EG: Approximately 300,000 women die due to pregnancy-related issues, many of which are preventable. Access to basic healthcare and assistance is crucial. It seems logical that improving access to healthcare and nutrition would reduce child mortality rates.
RM: Absolutely. Medical science has made significant advancements, and in industrialized countries, we’ve managed to reduce birth-related mortality to a few per hundred thousand. However, the United States has one of the highest maternal mortality rates among industrialized nations. A concerning case is Texas, where maternal mortality rates doubled after 2011, likely due to the closure of many prenatal clinics.
EG: That’s a shocking example of how decreased access to healthcare can lead to increased mortality rates for mothers and infants. Despite these statistics, things are improving globally for women and infant care. Over the last hundred years, the percentage of children dying between ages 0 and 5 has decreased by forty percent.
RM: Yes, and while the situation in the United States is concerning, medical interventions have significantly reduced death rates. However, the challenges are much greater in developing countries, particularly in Africa, where health provision is lacking.
EG: We have the benefit of technology and medical resources that could potentially be available to everyone. Access to healthcare and education has saved 122 million children. What do you envision for the future if everyone had access to healthcare?
RM: The key to improvement is prenatal care, which has already made a significant difference. Unfortunately, some people mistakenly believe that cesarean births are the easy solution, avoiding the challenges of natural childbirth. The World Health Organization recommends that cesarean births should only occur in about one in ten or one in seven cases, but in the United States, it’s currently one in three. This trend has serious implications, as cesarean births come with risks and side effects. If we’re not careful, we could end up with a situation similar to that of bulldogs, where a high percentage of births are cesarean due to anatomical issues.
EG: I’m grateful for mothers everywhere!
