Darwin’s principle of evolution is summarized by the following facts. All life tends to increase: more organisms are conceived, born, hatched, germinated from seed, sprouted from spores, or produced by cell division (or other means ... 2. Replicating molecules evolved and began to undergo natural selection. All living things reproduce, copying their genetic material and passing it on to their offspring. Thus, the ability to copy the molecules that encode genetic information is a key step in the origin of life — without it, life could not exist. Evolution of the atmosphere, process by which Earth’s modern atmosphere arose from earlier conditions. Evidence of these changes, though indirect, is abundant. Sediments and rocks record changes in atmospheric composition from chemical reactions with Earth’s crust and biochemical processes associated with life.7 Main Stages of a Star. •••. Updated April 16, 2018. By Bryan Roberts. Stars such as the sun are large balls of plasma that inevitably fill the space around them with light and heat. Stars come in a variety of masses, and mass determines how hot the star will burn and how it will die. Heavy stars turn into supernovae, neutron stars and ...

The larger its mass, the shorter its life cycle. A star's mass is determined by the amount of matter that is available in its nebula, the giant cloud of gas and dust from which it was born. Over time, the hydrogen gas in the nebula is pulled together by gravity and it begins to spin. As the gas spins faster, it heats up and becomes as a protostar.

Such divergent evolution can be seen in the forms of the reproductive organs of flowering plants which share the same basic anatomies; however, they can look very different as a result of selection in different physical environments and adaptation to different kinds of pollinators.
