The distribution of related animals and plants across the world shows that those organisms have common ancestor.
There is a term in biology- the most recent common ancestor (MRCA) and it is the most recent individual from which all the organisms are directly descended. It is hard for scientist to identify the exact MRCA, but it is estimated the time at which the MRCA lived (3.5 to 3.8 billion years ago). It is called Last Universal Common Ancestor (LUCA).

The answer is; in the summer
Insects such as blowflies increase their population in the summers when the temperatures are warm. One reason is that most insects are ectotherms hence their body temperatures are dependent on ambient environmental temperatures. In addition, the maggot stage of the blowfly pupates mostly in warm and dry conditions hence increasing winged flies populations in the summer.
As the ball rises it DECREASES kinetic energy which means it INCREASES in gravitational potential energy
