Main summary 
Just one person adds 37 million bacteria to the air every hour. A team of scientists measured the micro organisms in a classroom over a period of 8 days. 4 days it had people in it and 4 days it was empty. Humans in the room made a lot more fungi and bacterial particles. Scientists concluded that 18% of the bacteria was made by the human occupants. Of the 15 types of bacteria 4 were made by the humans including the most abundant Propionibacterineae. Carpets add bacteria but it doesn't mean that carpets should be removed. 

 I think that this is good that the scientists found out about this. But I think its very bad that a single person adds this much bacteria to a room. Even worse they add the most abundant one.

Main summary

We all know that scientists think that we evolved from monkeys. They aren’t sure from which one. A group of scientists compared human and monkey genomes. They’re discovery is that a lot of parts of the human genome resemble the gorilla genome more than they do the chimpanzee genome.15% of human genome resembles gorilla genome and 15% of gorilla genome resembles chimpanzee genome.

My thoughts

I think that this is a cool discovery and that this will help a lot with discovering the evolution of humans. The only problem is that testing is hard because gorillas are endangered species and some other monkeys are to. I wonder what we evolved from and those that animal still exist or did it evolve into another animal and then become extinct.
