My name is Sarah.
My life consists of video games, Harry Potter and art.
I am currently obsessed with the Avengers, and all things Tom Hiddleston. Apologies if this displeases you.
I reblog a lot of bullshit.
Until I can think of something more eloquent, this is all you need to know.
Mutation: it is the key to our evolution. It has enabled us to evolve from a single-celled organism into the dominant species on the planet. This process is slow, and normally taking thousands and thousands of years. But every few hundred millennia, evolution leaps forward.
