1) what evidence is there that the human species has been successful so far? explain.
2) what environmental pressures in the past do you think were most important in shaping the human species as it exists today?
3) what environmental pressures exist now that you think may be shaping the human species?
4) what environmental pressures do you think may affect humans as earth becomes more populated with humans in the future? explain how these pressures may affect human traits.

1) in terms of biology, a successful species is the one that survived: so human species is successful because it survived in big numbers

2) humans evolved on savanna, in Africa so one such pressure would be being able to spot predators from a distance - it contributed to us being upright

3) now the pressure is access to limited resources - food and technology

4) I think the pressure will be good-quality food and quality of life and the way it will influence humanity is by forcing people to have less children
