Itβs tempting to look back into history with rose-tinted glasses. Most people in the Stone Age didn't live anywhere near as long as we're living now. Today we can enjoy a more wide-ranging diet and we have fruit and vegetables available all year round.
As an anthropologist, I believe strongly in our common humanity. We can rise above the tribal divisions that have caused so much anguish and real damage in the past.
Archaeology can be overlooked as a discipline, I think, but itβs incredibly important to have this other way of approaching the past - not just through historical documents, but through actual physical remains - objects, buildings and the layout of our towns.
Around 4000BC, the Mesolithic, hunter-gatherer way of life here gave way to a more settled, farming existence. Those Neolithic people built wooden trackways across the salt marshes and reed beds.
So I think as a biologist I would like us to focus on this planet and finding solutions to sustaining humanity, to improving people's lives globally, but doing our absolute utmost to preserve as much biodiversity as we can, knowing that we have already been responsible for the loss of thousands of species.
We need to stop being so profligate with fossil fuels, to rein back climate change and protect biodiversity. We need to work together, globally, and Iβm optimistic that we will.
Evolutionary biologists have long pondered the phenomenon of the changing colours of autumn leaves. Itβs possible that the red pigments are manufactured in the leaf as a side-effect of something else thatβs happening at this time.
I know a bit about vertebrate anatomy and Iβd like to think that Iβd spot if a skeleton was entirely fabricated or cobbled together from existing bits and pieces.
I donβt think anyone is saying that we should be treating boys and girls exactly the same and that we should try to eliminate all differences. What the psychologists who do this work are saying is we should be aware of it and careful about it, especially if we think it could be limiting choices.
At Bristol I found it quite difficult to continue trying to balance three things - teaching, research and public engagement, for which television was obviously the most prominent part.
I was effectively unemployed after my son was born. I resigned from Bristol because I wasnβt happy with the way my career was going then discovered I was pregnant when I was out of a job, but I was freelancing.
I love prehistory - particularly the Neolithic and the Bronze Age. These were times when our ancestors made a revolutionary change from being hunter-gatherers to being farmers, and when great migrations of people spread languages - and genes - across Europe.
Pagan Romans started their midwinter celebrations with the feast of Saturnalia on 17 December, ending them with a new year festival, the Kalendae Januariae, at the start of January - both were celebrated with parties and the exchange of gifts.
The colour of a British wood in autumn is predominantly yellow. There are relatively few European trees which have red leaves in the autumn. But there are splashes of crimson or rust-red colours from a few indigenous trees, like the rowan, as well as from introduced species, like the North American red oak.
Lunch on the road is usually the same as breakfast and tea in remote places - packet meals. I'm veggie and generally get vegetable curry or rigatoni.
After a few days of vegetable curry I crave my husband's home-made pizza.
I was extremely lucky as I was in one of the last generations of British students who went to university and had my fees paid, and I had a grant as well. I also earned money from my waitressing and designing and selling my own range of dinosaur cards.
Iβve seen many dinosaur fossils, some mounted in museums, others in the process of being extracted from their rocky matrix, and it has never occurred to me that any could be anything other than genuine.
While planting woodlands along rivers has been shown to work in small areas, it has been unclear whether it would be effective on a larger scale. But computer modelling indicates that restoring forests on floodplains could slow floodwaters and reduce the height of the flood downstream.
Our long, flexible lumbar spines are great in many ways - they help us to run efficiently, for instance. But they have their drawbacks. The lumbar vertebrae are under great strain, and as we age, the ligaments that hold the pulpy centres of the intervertebral discs in place dry out.
