Answer 1

1.)earths atmosphere that allows accumalation of gases(most importantly carbon, hydrogen, oxygen, and nitrogen)

2.) the formation of earth at the perfect distance from the sun in which water can assume a liquid form.

3.) formation of genetic material and thus reproduction. this allows mutation and higher diversity which means better chances of survival.

4.) formation of single celled organisms and then multicelled organism which eventually over a great time span lead to specialization of cells.

5.) specialized cells that allowed for more complex and adaptible organisms.
