In the first two decades of the 21st century, we have witnessed an extraordinary and unprecedented advance in biology.
We have made enormous progress in understanding how life arose on earth and how it is connected to other life forms.
But, as we know from our experiments, life has a number of challenges that are beyond our grasp.
How does life exist in a world with so many competing competing and competing needs?
And how do we deal with the fact that life is constantly changing, adapting to environmental conditions, and evolving?
How do we manage these processes in a way that maximises the chances of the survival of the species?
These are the challenges we have to tackle if we are to live with a future of human population, biodiversity and global warming.
So what is life?
What is the relationship between biology and biology?
And why do we need to know all these things?
What does a human organism look like?
Why do we make babies?
How did we become part of nature?
And what are we doing to protect our future?
As the number of people in the world grows, we will need to find ways to understand more about these complex and challenging questions.
This is the story of human embryology and the development of the human species.
