The Lost One
Some people who aren’t good in biology (from my experiences here, most of them are creationists), think the “survival of the fittest” means being the “strongest”, “smartest”, or other qualities.
That’s not what it meant in evolutionary, biological term. And it has been over hundred of years since that term was coined, people (eg creationists), even today, still cannot understand what it mean.
It all have to do with being able to pass the necessary genetic changes - the physical traits - to future generations that they not only survive the changed environments, but to thrive in the environment.
Every species of every organisms that are here today, are living examples (evidence) of Natural Selection or Mutations or Genetic Drift. Each species and subspecies that are here today, have found niche in which can survive and thrive.
Take for instances the differences between brown bears and polar bears. Polar bears didn’t exist prior to 2.5 million years ago, the polar bears actually evolved from earlier brown bear species.
The brown bears before the start of the Quaternary glaciation, are similar to the ones that exist today, they hunt for food during the warmer seasons, and hibernate during the colder seasons, each years.
The recent Ice Age - the Quaternary glaciation changed the environments, where the ice sheets covering extensive regions in northern Europe, Asia and North America. And these glacial period could last any from thousands of years to tens of thousands of years, where there were no annual warmer seasons (eg no summer).
When those ice sheets covered regions for thousands of years with no summer, animals that found themselves in these regions with no summer in their lifetime, must adapt to these conditions, or else, these animals faced extinction.
Among the animals trapped there, in the regions covered in ice, were the brown bears. The changes didn’t change overnight, and it was more than obvious changing the color of their fur from brown to white.
One of those changes, were not hibernating, the brown bears can no longer afford to hibernate, because otherwise they will starve. So they must hunt and eat even in the most coldest period. And what they must consume were lots of fat, so their diets changed, so their main prey were sea seals and sea lions, instead of fishes and other meats they could catch on icy land. The more fat they eat, the more body fat they would retain, because fat are better at insulating the body for warm than lean muscles.
And since their preys were animals with lot of body fats, they must become even better swimmers than other species of bears. Their paws are longer than most other species of bears, which give them better propel in sea water, but also their claws have changed to, that gave them better grips on ice. Most bears can swim, but the polar bears are capable of staying in freezing sea for days if necessary.
And more than change of color of their furs or hair. Sure, white gave them better camouflage, but the textures of hair, fur and hides have changed. The changes gave them better resistance to icy wind and better water proofing in sea water.
As I said, the changes came slowly for brown bears to evolve into what we currently see today as polar bears. It would have taken hundreds of generations.
These changes - the evolution - don’t involve 3rd party, like the Intelligent Designer, directing changes. The very notion of the ID Designer is absurd, and it exactly the same absurdity of GOD or CREATOR.
Now, creationists tried to switch gear, thinking (evolutionary) changes required there be “purpose”, “intention” or “design”...or else Evolution isn’t true.
The only things that are true, are the ways that creationists continued to be misinformed in even the most basic biology concept. They have even created another form of Creationism - Intelligent Design - but this too failed to be science, because its main focus is on PR propaganda and trying to use political, legal and social pressures to force education organizations to teach creationism in classrooms.
ID Creationism have nothing’s to do with natural science, and nothing to do with natural reality. It is just more of the same superstitions of Genesis CREATOR. All ID is doing is giving God a different title, Designer.

Everybody who understands science already knows this - and has been trying to tell stubbornly ignorant creationists who ask for 'proof', for years.
And because I could memorize pretty well, grasping concepts, I did rather well in school as well.
