Crystal Clear: The evolution of the eye, part 2

“I am inclined to believe that in nearly the same way as two men have sometimes independently hit on the very same invention, so natural selection, working for the good of each being and taking advantage of analogous variations, has sometimes modified in very nearly the same manner two parts in two organic beings, which owe but little of their structure in common to inheritance from the same ancestor.”

Charles Darwin, The Origin of Species

To put Darwin’s statement in other words, it looks very much as if the processes of evolution have hit upon the same solution multiple times. Continue reading

How much does the natural world feature in the average Christian’s relationship with God? Church leaders often speak about ‘discipleship’, meaning the process of learning what it is to be a Christian and putting that knowledge into practice. The question is, are discipleship and our experience of the created order – trees, water, rocks and stars – held in separate watertight boxes, or are they blended Continue reading

The deadly marine wonder, the Portuguese man o’ war, resembles a jellyfish with its beautiful blue and purple ship-shaped bladder and impressive 30-foot stinging tentacles. What may at first appear to be a single organism is actually a colony of four completely different types of polyp, working together so closely that they are not able to survive Continue reading

Imagination and Incredulity: The evolution of the eye

“To suppose that the eye…could have been formed by natural selection, seems, I freely confess, absurd in the highest possible degree. Yet…”

Charles Darwin, The Origin of Species

The ‘yet’, in Darwin’s introduction to ‘Organs of Extreme perfection and complication’ is very telling. The ideas that follow this oft-quoted sentence remind me a little of Paul’s letter to the Ephesians Continue reading

When I was three, I knocked a bucket of tadpoles all over on the patio. I remember the incident very clearly, so it must have been a relatively stressful one. It all happened Continue reading

The Genesis creation story may seem to be all about God getting rid of disorder and turning it into order, but that’s not how a physicist sees it. In her lecture at the Christians in Science conference in Oxford a few weeks ago, Dr Rhoda Hawkins explained why.

Hawkins studies how unpredictable events on a microscopic scale can produce something very predictable and useful on a larger scale. For example Continue reading

Guest Post: When is a person?

baby-605588_1920At what point in human development can we recognise the presence of another person like us?  It’s an age-old question which cannot be avoided, and I’ve been interested in the recent discussion about this on this blog.  Each one of us comes to this question from a different perspective, so I would like to offer some reflections from the perspective of a baby doctor. As a neonatologist I have cared for many tiny and fragile babies, some as small as 22 weeks of gestation and weighing less than 500g. Continue reading
