sick viruses sometimes
Viruses don't just make us sick. They can actually sometimes end up in our genomes.

Today, when we look at a brain, we see an intricate network of billions of neurons in constant, crackling communication, a chemical labyrinth that senses the world outside and within, produces love and sorrow, keeps our hearts beating and lungs breathing, composes our thoughts, and constructs our consciousness.
successful dna viruses
Parasites are not only incredibly diverse; they are also incredibly successful. There are parasitic stretches of DNA in your own genes, some of which are called retrotransposons. Many of the parasitic stretches were originally viruses that entered our DNA. Most of them don't do us any harm. They just copy and insert themselves in other parts of our DNA, basically replicating themselves. Sometimes they hop into other species and replicate themselves in a new host. According to one estimate, roughly one-third to one-half of all human DNA is basically parasitic.
cannot catching cattle creatures digest drinking grow kitten learned milk nurse people start stop
The people that domesticated cattle and started drinking milk learned how to digest it as adults. Normally, creatures after they grow up cannot digest milk easily. For instance, a kitten will nurse and digest milk, but then will grow up, stop drinking it, and start catching mice.
ancestors biggest book evolution evolve history human papers people questions scientific spent spring talking time walk
I read a lot of scientific papers on the history of evolution and spent time talking to scientists. I started to write it in the spring of 2004 and wanted the book to look at the biggest questions people have about human origins, such as what were the first hominids and how did our ancestors evolve to walk upright?

I'm really interested in the history of life in general. How life began to how birds evolved to what our ancestors looked like.
