when I was woven together in the depths of the earth.
Your eyes saw my unformed body;
all the days ordained for me were written in your book
before one of them came to be.
You began life as a single cell – a fertilised egg with mother and father’s DNA mingled together in a unique combination. This miniscule blob was all of you for a few hours, until it began to divide: 2 cells, 4, 8, 16, a ball, a hollow ball, and then something more complex. You were still tiny, but developing a nervous system, a head, a body, arms and legs. By that point your mother would be only too aware she was expecting a baby – the physical symptoms would have been hard to ignore. Continue reading →
How are babies made in the womb? From a sperm cell and an egg cell, an embryo is formed, which then becomes a fetus, and ultimately a baby. Different cell types for bones, skin, muscles, blood, and brain are just a small part of the complexity of human life. Unimaginable numbers of proteins, nucleic acids, and lipids (fats) of just the right kinds are also precisely located in exactly the right locations. Without knowing any of these scientific details, the psalmist wrote, “Thank you for making me so wonderfully complex! Your workmanship is marvelous—how well I know it. You watched me as I was being formed in utter seclusion, as I was woven together in the dark of the womb” (Psalm 139:14-15, New Living Translation). In a certain sense, God makes each baby; in another sense, the baby makes itself—with help from the mother and father, of course! Continue reading →
“The first time I peered down a microscope at a living sea urchin embryo when I was a graduate student at Berkeley I was absolutely hooked on developmental biology. Christians, when they’re doing science, are experiencing something that I call ‘doxological fascination’. In other words, they’re locked in on the minute details of something – which academics tend to do – and yet they’re doing it for God’s glory, in the same way that Johann Sebastian Bach wrote SDG (Soli Deo Gloria) in all the margins of his manuscripts. [I know a scientist who writes SDG on all her lecture notes and in her lab book – Ruth]. They’re trying to, in Keplerian fashion, ‘think God’s thoughts after him’.
I teach two main courses, cell biology and developmental biology. In each of these courses I start by telling the students that my main goal for the semester is that they would think cells, or embryos, are cool. They laugh, but I go on with this quote that I love:
The most beautiful experience we can have is the mysterious. It is the fundamental emotion that stands at the cradle of true art and true science. Whoever does not know it and can no longer wonder, no longer marvel, is as good as dead, and his eyes are dimmed.
I want them to be much better than dead by the end of the semester! My students don’t yet understand how incredible embryos are, and my goal in teaching biology is that they would not be the sort that are sitting around ‘picking blackberries’. I think that this is a new idea to some of my students, and it’s a touch point that I have in common with them, whatever their faith commitments are.
In my introduction to developmental biology I use some ancient Hebrew poetry, from Psalm 139, where David is musing about embryonic development. Even when he was developing in the womb, God was there and David uses poetic language to talk about how his own body was formed. He doesn’t understand that process, but he knows it’s fearful and wonderful. So I tell my students, whether you share David’s worldview – as I as a Christian happen to – or you don’t, by the end of the semester I want you to share this sense of wonder about the incredible intricacy of developmental biology and the processes that we have the privilege of studying. Usually in the teaching evaluations at the end of the semester there are lots of comments saying, ‘Wow, he actually cares about this material’.”
I love this example of someone who is passionate about his work, and who works hard to transmit that passion to his students. I meet so many people who are surprised that a scientist might think in this way – they feel as if science somehow squashes all the life and meaning out of things – so the more people who get to hear stories like this one, the better!
