King penguins have evolved to develop razor sharp bills ,

because it gives them a chance of beating off seals , their main predator , which wish to kill and eat them ,

they have also learned that they must face the seal head on
otherwise risk being killed , and the seal , as big as it is , realizes that face to face with a king penguin may actually get an eye taken out if its not careful , so the seal tries to grab them from behind when the penguins arent watchfu . Needless to say the young and the frail , the naeive are the ones that get eaten easiest .

It ensures a struggle is in place , an equilibrium , a random struggle which may see the penguin win or lose , come what may though the seal will definately get to eat some of them , since it needs to survive as well , and in turn , the penguin feast on herring , which every year do the same thing , in their millions their only defense is to roll themselves up into a swirling mass , in the vein hope they wont get eaten , but after an hour or two , all of them are gone , those herring have never learned over millions of years , Not so much as a gene passed on to make their offspring develop a nasty little barbed fin or two , so that all those predators cant gulp them down so easy .

yet if they did evolve this way , the planet as we know it , the one we love and enjoy would end .

Consider how many other creatures have never evolved to develop any defense against predators despite being attacked and eaten every year . But the king penguin like so many other creatures has passed on information to its offspring to advise them of how best to defend themselves .

But Plankton have never evolved over the millions of years theyve been around ,

we say that humans came from the sea , as small as a plankton they would have been at one stage , so if thats true we can expect that other micro organisms also have a fair chance of evolving over many millions of years , at least becoming more intelligent , yet if plankton ever did develop a defense to being eaten by the dozens of creatures which rely on them the world would cease to exist .

It might be argued that the sheer amount of plankton that spawn are the planktons way of defending itself , in huge numbers so that they always ensure many other millions will survive . But what of this evolving intelligence scientists speak about ?

why do you think plankton have never evolved ?


Plankton have evolved. Many species evolved from species of plankton, and those plankton species that are around today are not identical to the plankton that existed millions of years ago.
But they are quite similar. The reason they remain similar in size, shape and function is because there remains the evolutionary niche of small processors of organic matter in the ocean.
As a thought experiement, imagine that all species of plankton had evolved in such a way that there were no longer any microscopic plant and animal organisms (it really isn’t possible, considering the diversity of the species they support, but just imagine). The ocean would be rife with decomposing animal and plant particulate, an abundant supply of nutrients. There would be a totally unused source of energy everywhere in the ocean. The extraordinary size of this resource makes its existence impossible.
As the benefits increase, there is more and more selective advantage to entering an evolutionary niche, and plankton remain because the niche the occupy has existed continuously throughout bio-history time, and will continue to exist as long as plants and animals die and disolve in the oceans.

But . . . plankton are evolving:

Is an example of the research being done on the phylogeny of plankton.

Also, herring have a much larger selective pressure than penguins: migration. Like everything else in life, adaptations are trade-offs (see: why don’t humans have a tail?), and sometimes the juice ain’t worth the squeeze. Protective measures from Penguins could either impede herring motility, or cost just enough extra energy to make it not worth it.

because he can’t get the recipe to the crabby patties.


Theres no proof of that

I understand that , obviously there will have been some slight adjustments , but essentially plankton have remained the same , as many other species have , there has been no evolution

Thats was my point


Evolution can be as small as an appendix, an extra miniscule bit of intestine an extra scale or even an action. Need = evolution, Learning = evolution, Change of habitat = evolution. There are many ways of evolving, changing and there are many causes for such.

Some evolution can only be found under a powerful microscope. It is still evolution. If it is a species of life, it evolves whether we see it or not. There are so many things for scientists to study and so few scientists, what we do know is easier to list then what we don’t know. When it comes to the study of the universe, this world and all species, our knowledge is pitiful but, it is growing and evolving slowly. Don’t think with a blind eye, think with eyes wide open,moving and closed. What you see involves many many many things you don’t see and will never see.

Keep in mind 200 years ago the scientific community did not have the research tools available today. So there are no indepth comparitive studies. 200 years ago plankton was not really a topic for research. Heck 50 yrs ago it was not really a topic.

Also to do a decent genetic evolutionary comparitive study they would have to find intact ancient plankton embedded in Ice, amber or other element that would keep ancient bodies intact. They would have to find plankton from different eras to be positive and find a good quantity of each. then they would have to be positive of the dating. Talk about a needle in the haystack.

My point was that there continues to be an evolutionary niche for plankton. The selection preassure tends to keep them adapted for the niche they are in, so tends to keep them relatively the same.

Actually, since there is observable genetic drift within the plankton populations at different locations, that is proof that they are evolving.

But they have powerful microscopes and havent found anything much in the way of evolution as far as I know

To me thats a bit like saying god is there whether we see him or not , it becomes scientific faith , even though there is not much evidence that things continue to evolve the way they used to

And we make all our conclusions based on this pitiful knowledge , I think creatures evolved , but it seems they have got to a stage where they dont evolve anymore since they are basically perfect , Im sure somethings will look a bit different in a million years , but most things are perfect , you couldnt change anything on a salmon that wouldnt have dire consequences for the rest of nature , its perfect , as many species are


But its not actual proof


DoL, when we speak of a species “evolving,” what that means is that its descendants show different properties and eventually are classified as new species. We don’t mean the organism ITSELF changes. Also, one can get a misimpression from the idea of natural selection that evolution happens when a species is poorly adapted to survive; that’s not really so.

Evolution is a process of controlled change in life. Natural selection doesn’t drive the change, it provides the control. Mutation and genetic drift drive the changes; natural selection kills off changes that have no niche to fill. A species can be perfectly adapted to its niche, needing no changes to survive, and its descendants can still emerge as a new species if there is a new niche to be filled. It’s not always survival pressure, but more often the existence of empty niches, that allows evolution.

Look at what happened with mammals, which evolved roughly the same time as dinosaurs. Dinosaurs dominated animal life and filled most of the niches, so mammals were confined to being small predators and small herbivores throughout that whole period. When the mass extinction happened that killed off the dinosaurs, niches opened up, and mammals evolved new forms to fill them. But those small predators and small herbivores that the earliest mammals were are still around, not the exact same species but very similar ones filling those same niches. It’s just that now there are a lot more varied forms of mammals, filling the niches that were once filled by dinosaurs.

Same with plankton. It’s still around because it’s a niche to be filled. But life has evolved into many new forms to fill niches that plankton doesn’t.
