Certainly the body isn’t one part but many. If the foot says, ‘I’m not part of the body because I’m not a hand’, does that mean it’s not part of the body? If the ear says, ‘I’m not part of the body because I’m not an eye’, does that mean it’s not part of the body? If the whole body were an eye, what would happen to the hearing? And if the whole body were an ear, what would happen to the sense of smell? But as it is, God has placed each one of the parts in the body just like he wanted. If all were one and the same body part, what would happen to the body? But as it is, there are many parts but one body. So the eye can’t say to the hand, ‘I don’t need you’, or in turn, the head can’t say to the feet, ‘I don’t need you’. Instead, the parts of the body that people think are the weakest are the most necessary.
(1 Corinthians 12.14 –22, CEB)
In this passage, St Paul is referring to parts of the body that we can see, but equally important are the millions of molecular machines and processes that we cannot see but nevertheless sustain our every Continue reading →
I remember touring an auto manufacturer several years ago in the United States. The whole factory was a wonder to behold. Tiny parts started on an assembly line that eventually became, at the end of the process, a completed car. Hundreds of workers added parts and pieces to an unfinished vehicle slowly over time until, eventually, it would become a complex functioning vehicle. A wheel in the wrong place or Continue reading →
A horde of salmonella bacteria invades a mouse’s guts. The rodent’s immune system is on the alert, but something unusual happens. A minority of the invaders throw themselves onto the mouse’s colon bugs, even though their attack is too risky and they die. Their comrades take advantage of the breach, yet they are not as aggressive themselves.[i]
The berserk salmonella “are prepared to sacrifice themselves for the greater good”, a researcher explains. “You could compare this act to Kamikaze fighter pilots of the Japanese army.” This scenario raises the question, did they do that on purpose? Of course bacteria do not have conscious intentions, but it is at least possible that in another sense there is genuine purpose in this behaviour. This is also an important point from the perspective of Christian faith, which involves belief in a purposeful divine creation. Continue reading →
Every person was once a sperm and an egg. Those two unique germ cells fused together, and in nine months they turned into a living, breathing, human being. Each of us emerged from the same Continue reading →
As someone with largely European ancestry, 1-4% of my DNA is likely to have come from Neanderthals. My mother had red hair, my whole family have white skin, and we are relatively well adapted to the cold. These characteristics could all be faint traces of our Neanderthal ancestry. My friends from the Far East will probably also share a little of their DNA with another race of hominins* called Denisovans, and Africans with yet other ancient hominins.
I recently heard a new metaphor for the gene. Although this phrase was coined by a physicist*, I think it’s an interesting one. The concept of ‘The Eager Gene’ comes from Andrew Steane, Professor of Physics at Oxford University, in his book Faithful to Science (see previous blog).
Steane writes that “Genes are, of course, inanimate molecules, having no eagerness or moral capacity, but Continue reading →
Identical twins are living proof that our genes contribute to, but don’t completely determine our behaviour. But what about our faith? Does our DNA affect our beliefs or how we express them? Denis Alexander and Nell Whiteway have spent the last couple of years working on a project at the Faraday Institute ‘Genes, Determinism and God’*. Nell spoke on the genetics of religious behaviour last month, as part of the Wesley Methodist church Science meets Faith lecture series.
Any parent of identical twins knows that identical DNA does not equal identical personalities. On the other hand, twins do share many characteristics – even if they grow up in separate families – which makes them an ideal population for geneticists to look at. Continue reading →
