Looking in detail at human anatomy, I’m always left with two practically irreconcilable thoughts: our bodies are wonderful, intricate masterpieces; and then - they are cobbled-together, rag-bag, sometimes clunking machines.
It’s incredible that the layout of the centre of Chester, for instance, is still essentially that of the original Roman fort.
Then the BBC approached me in 2005 and asked me to be one of the presenters of the series 'Coast', which turned into a very long-running series.
In Luke, shepherds go to find Jesus. In Matthew, an unspecified number of wise men, sometimes portrayed as kings, arrive. Nativity plays usually throw all the elements together, with kings and shepherds beating a path to the stable.
In our evolutionary narratives, the organism itself often seems to play a passive role: a powerless victim, almost, of changes to its environment or mutations in its genes.
Chance is hugely significant in biology. In fact, the presence of apparent randomness in so many aspects of biology - from mutations in DNA to the chance involved in that one sperm reaching that one egg that became you - suggests that randomness is useful, even necessary, in very many cases.
Look what consumer power has done with organic food; we can do the same with clothes.
I gave up meat when I was 18, and it was an ethical decision. I loved the taste, and went on holiday to Greece, fairly gorging myself on lamb souvlaki before taking the plunge into a meatless existence.
Easter is an ancient festival of rebirth, but it’s also an excellent excuse for eating eggs. I really like eggs, of both the chocolate and chicken variety. But the chocolate ones, you must admit, can sustain only a fleeting interest. A sweet, sugary hit - and then it’s gone.
And when you take something like the changing colour of autumn leaves and start to ask why, you’re starting off on an intellectual journey which will take you beyond that moment of visual satisfaction, while robbing nothing from that experience.
I consider myself to be a relatively sceptical person. I like to see evidence for myself, and try to avoid speculating beyond available evidence. But I also have to accept some things on trust.
The scientific method is about trying to remove our own bias and subjectivity, and be as objective as possible. But then you can put it back into context and you’re allowed to be emotional and human about the way you engage with it.
Biological anthropology tends to focus on skeletons because that's what is often left behind in the ground, but I am a whole-body anatomist, I'm a clinical anatomist and that's what I teach, I teach it all, not just the skeleton, the muscles and nerves, blood vessels.
I love Christmas. At this very special time of year, when the sun appears only fleetingly to those of us living in the northern hemisphere, I feel a deep connection with ancient ancestors.
But I think you can strip the emotion and the subjectivity away while you focus on doing the science - and that’s really important.
Always attempting to tame and subjugate nature is not the solution. But the latest science is helping us to map out a path across this shifting landscape in uncertain times, showing us how to work with natural forces, not against them.
As well as tasting fantastic, blackberries are good for you. Anthocyanin isn’t just a pigment, it’s a flavonoid, a heroic antioxidant! The stuff of superfoods!
In fact, humans have less variation genetically than chimpanzees.
You’re not tapping into the widest possible pool of talent if you’re shutting some people out of particular careers.
