So /sci/ is there such thing as a truly "more evolved" creature?

For those that believe there are, what objectively justifies something as "more evolved"?

Everything is at the top of its evolutionary chain...

Let me just play the devil advocate with this analogy...
Think of two type of digital cameras with two different settings:

1. A low-light (long exposure) setting
2. A high speed setting.

Both cameras had different traits and they are specialized for different purposes.

A long exposure camera setting allows us to see in a much darker light range and is much better of at capturing images in the dark but it lacks the ability to capture thing moving at a fast speed as they turn out to be blurs. Is also overexposes and is useless in a bright environment.


In contrast, a high speed camera can capture fast moving targets clearly. This comes at the expense that the camera must be placed in a bright environment with lots of light otherwise it underexposes and the image is useless.


But consider this, supposed you were to spend more money on a higher end camera with a quality sensor that had a very high ISO. In this case you would not only have a camera that could capture images in low light setting but could also capture at a high speed.

My argument is equivalent to expanding the Pareto frontier and increasing production in all areas. The ideas is similar to how disruptive technologies can render previously existing tradeoffs obsolete. How does this not, in an evolutionary view, correspond to a more evolved creature?

Hey yáll. Dumbass here.

Can /sci/ help me become more intelligent? I ain't talking about that IQ shit, though. I know if I took an IQ test, I could study the results and do better if that's what I cared about. I'm talking about real intelligence, spatial awareness, critical thinking and all that other good shit.

Give me some advice, ya filthy geniuses.

And no one here is that smart.
Educated =/= intelligent

>>8544597
I mean, I don't even know what my IQ is, and I don't think that's too important(maybe I'm wrong). People like Einstein, Newton, and Von Neumann aren't famous because of their high IQs, rather they're famous because of their achievements.

Is it possible for a dumbass to have incredible achievements that could be put in comparison to the dudes above?

Alright guys, Theoretical physics student here, second year. Thinking of being a teacher, because surely the most effective way of contributing to science is inspiring many more to go on to do science. The only problem is I don't want to live the rest of my life with people applying the old phrase 'If you can't do, teach' to me. I know I'd be a good teacher, but would it be worth it? Any teachers/lecturers/tutors here to help me out?

Is bioinformatics a good field to get into if I want to solve interesting problems using programming?
12 posts and 1 images submitted.
>>
not really

bioinformatics is a tool for biologists/biochemists
for example a software that contains a complete dna code of a specie, so instead of having to write all the base-pairs down they can just use a database

as a programmer it would be just like any other field, you make develop a software that's it
regardless of its function, you won't help solve any bio related issues
>>
>>8543663
You talking about bioinformatics software as used biologists and biochemists, which is really within the scope of those disciplines and not the field of bioinformatics itself.

It's like saying there aren't many interesting problems to solve in cartography because you won't help explore the world.

In the field of bioinformatics proper there are many interesting, domain-specific problems to solve both on the algorithmic level (e.g. in genome assembly) and in fiddly high-performance implementation details which could be of interest a computer scientist and programmer.
>>
Sure. Dedicated bioinformatics researchers are mostly CS/math transplants who are applying high-level information and CS theory to biological problems. Some of them don't even touch biological data ever, they just work on tool development.

If you think you can eke out a little more algorithmic efficiency from mapping alogrithms or statistical modeling, then go for it. Everyone in biology would be grateful.

Hello sci

How do plants 'know" what evolutional traits to develop?

It seems logical that a tree adjusts itself to arid environments or heals it's wounds with sap.
What about interaction with other life forms or things not directly in contact with them though?
Developing signal colored, sweet seed containers for animals to eat, so they drop them a few miles away; or seeds with propellers, which get carried away by the wind.

Any links or information?

>How do plants 'know" what evolutional traits to develop?

They don't. The traits they develop are random and the useful ones hang around
>>
>>8543340
same way animals know
>>
>>8543346
So everything not having these traits just went extinct?

Please give me citation if possible.

A medical question for you peeps.

Over the past 6 or so years, I have had between 10 and 25 warts on my hands, depending on the time. Some died, others formed later, and some I have had for the past 6 years altogether.

During this long amount of time, I have tried everything from tea tree oil, to duct tape, to cryotherapy (the only one that actually worked). About 4 months ago, I took Claritin for the first time to prevent some seasonal allergies, and all of a sudden most of my warts started to dry up and die. To further back this up, I quit taking the Claritin for about a month, and the ones that were left stopped drying up and stayed. After taking the Claritin again, I have had several more die.

I have looked everywhere for research documents on allergy medicine helping prevent or treat warts, and absolutely nothing comes up. Does anybody here have any experience with this or know something that I am missing? Is there a possibility that the Claritin is helping to kill the warts?

Perhaps you're allergic to something in the air and the claratin helps that?
>>
>>8543034
What is odd is that the warts will form in areas that get wounded, like papercuts or scratches that drew blood.
>>
>>8543020
Shit, you know I think I might actually know.
So the chemical in claritin is some lipid that is basically in the same category as accutane. Accutane can treat not just regular acne, but its good for really weird skin shit. Like sebaceous cysts and stuff like that. So that could be it. I'm in bed ill check my notes on this tomorrow

Summary of consequences:
>U.S.-Russian war producing 150 million tons of smoke
>2600 U.S. and Russian strategic nuclear weapons on high-alert are launched (in 2 to 3 minutes) at targets in the U.S., Europe and Russia (and perhaps at other targets which are considered to have strategic value).
>Some fraction of the remaining 7600 deployed and operational U.S. and Russian strategic nuclear warheads/weapons are also launched and detonated in retaliation for the initial attacks.
>Hundreds of large cities in the U.S., Europe and Russia are engulfed in massive firestorms which burn urban areas of tens or hundreds of thousands of square miles/kilometers.
>150 million tons of smoke from nuclear fires rises above cloud level, into the stratosphere, where it quickly spreads around the world and forms a dense stratospheric cloud layer. The smoke will remain there for many years to block and absorb sunlight.
>The smoke blocks up to 70% of the sunlight from reaching the Earth's surface in the Northern Hemisphere, and up to 35% of the sunlight is also blocked in the Southern Hemisphere.
>In the absence of warming sunlight, surface temperatures on Earth become as cold or colder than they were 18,000 years ago at the height of the last Ice Age
>There would be rapid cooling of more than 20°C over large areas of North America and of more than 30°C over much of Eurasia, including all agricultural regions
Tfw it can actually happen.

>150 million tons of smoke in the stratosphere would cause minimum daily temperatures in the largest agricultural regions of the Northern Hemisphere to drop below freezing for 1 to 3 years. Nightly killing frosts would occur and prevent food from being grown.
>Average global precipitation would be reduced by 45% due to the prolonged cold.
>Growing seasons would be virtually eliminated for many years.
>Massive destruction of the protective ozone layer would also occur, allowing intense levels of dangerous UV light to penetrate the atmosphere and reach the surface of the Earth.
>Massive amounts of radioactive fallout would be generated and spread both locally and globally. The targeting of nuclear reactors would significantly increase fallout of long-lived isotopes.
>Gigantic ground-hugging clouds of toxic smoke would be released from the fires; enormous quantities of industrial chemicals would also enter the environment.
>It would be impossible for many living things to survive the extreme rapidity and degree of changes in temperature and precipitation, combined with drastic increases in UV light, massive radioactive fallout, and massive releases of toxins and industrial chemicals.
>Already stressed land and marine ecosystems would collapse.
>Unable to grow food, most humans would starve to death.
>A mass extinction event would occur, similar to what happened 65 million years ago, when the dinosaurs were wiped out following a large asteroid impact with Earth (70% of species became extinct, including all animals greater than 25 kilograms in weight).
>Even humans living in shelters equipped with many years worth of food, water, energy, and medical supplies would probably not survive in the hostile post-war environment.
