IS ANOTHER HUMAN LIVING INSIDE YOU? KEY AND TEACHERS’ NOTES
This fascinating text describes the real story of where we come from and as such comes up with surprises about our biological make up. The note making exercise at the beginning is very important as it introduces students to an alternative way of exploiting a reading text if there are no questions. The podcast is rather mechanical but after much deliberation I chose to include it; however, you can do as you wish.
1.       Incomplete
2.       Superorganisms
3.       The fact that a very large number of human and non-human individuals which are incessantly struggling inside us for control may influence our behavior
4.       Possible answer: microbes in your gut can have serious disadvantages and even cause death
5.       Chimera
6.       The twin who has been absorbed
7.       Yes, she gave birth to them; No, two of them carry the DNA of the twin she absorbed; she should be considered the surrogate mother of those two.
8.       Because the foreign tissue being directed by different genes carrying a different blueprint, may throw the intricate design of the brain into disarray.
9.       Because the individual started out as two fetuses but the twins merged during early development.
10.   By absorbing stem cells from her own son
11.   Because even non-identical twins may have sapped brain tissue.
12.   The term individual should be redefined
