Life definition.

[Sayonara]

Means, biology is not constant, is not accurate, and is not more than taking notes, and well is subjective because biology can be managed from very many point of view, and in physics for example. as physics law will be always the same liking it or not.

No offence intended, but you are clearly speaking from ignorance. 90% of biology is maths. The other 10% is some of the most rigorous peer review you will ever see. If you think physicists all have the same point of view on the subject you have been grossly misled somewhere.

 

 

I did started the other one first (thread), i did this one in order to see which one you consider the life definition is.

And yes you can sayonara, actually i did already.

It proves biology is not a science. and i´ve thinked it much hard.

Somewhat pointless, since there are plenty of threads on the subject already that do not start with a completely biased point of view.

Also my point was that you ought to understand what the currently accepted definition of life is before starting a thread about whether or not it applies to computers; and you clearly do not.

 

 

If you disagree take one of my challenges and prove it the science way.

I have already responded to one of your challenges.

[Sayonara]

Additionally, if you are so worried by subjectivity, would it not be a good idea to tell us what attributes you think qualify a discipline as a "science"?

[AtomicMX]

i will...

[AtomicMX]

BTW More than math are statistics... and probability.

and much chemistry.. and biologist notes btw.

 

and about the life definition, i started that thread by the cause you said, but actually there is a life common life definition.

 

All this troubles of conceptuality come from the subjectivity of biology.

[Sayonara]

Having studied biology for a good number of years and earning my degree in that subject' date=' I think we can take it for granted that I don't need you to tell me what is involved in the biological disciplines.

 

 

and about the life definition, i started that thread by the cause you said, but actually there is a life common life definition.

Tell all.

 

 

All this troubles of conceptuality come from the subjectivity of biology.

No, I don't think so. I think it's more likely they come from you not knowing enough about biology to come to accurate conclusions. Anything will seem subjective if you don't have the information you need to objectively evaluate it.

[AtomicMX]

Well set that up in the debate ok?

[dagaz]

Biology is supposed to be a science. then...

Which is the approved life definition "by the science"?

 

Life is incredibly complex so you are never going to a get a nice all-encompassing definition which you can put into one sentence. Although there are some grey areas still under debate, nearly all biologists would agree with the following characteristics of a living organism:

 

1) able to metabolise - that is they can use energy to accumulate, modify, produce and eliminate materials which are necessary for growth and reproduction.

 

2) have the capacity for growth, development and reproduction.

 

3) contain DNA which provides inheritable genetic traits.

 

4) use homeostatic responses to minimise the effects of changes in the environment.

 

5) show adaptive potential which will allow them to respond to long term changes in their environment through evolution.

 

6) cell theory also tells us that all living things are made from cells.

[AtomicMX]

I loved your life definition, but what about RNA?

[admiral_ju00]

what about it?

[AtomicMX]

I suppose they include RNA with the DNA definition..... or not?

[admiral_ju00]

yeah.

 

{edit}

 

but since you question the very many basic things of biology, perhaps you can elaborate on this?

[AtomicMX]

now i love that definition.

[admiral_ju00]

damnit, i should have read the post #32, but if you're reffering to this:

contain DNA which provides inheritable genetic traits as the definiton for RNA then, no.

[AtomicMX]

yeah.

i didn't understand

[AtomicMX]

and... now i do not love so much the definition

[dagaz]

I suppose they include RNA with the DNA definition..... or not?

 

Kind of, as RNA is synthesised from DNA, however it is responsible for protein synthesis rather than genetic traits. The reason RNA is not specifically mentioned is because it is not present in viruses or certain primitive procaryotic cells.

[Skye]

Well some viruses have RNA, and those that do don't have DNA.

[dagaz]

Which is part of the reason that viruses are still under debate as to whether they qualify as being a living organism - the other being that they can only reproduce in other cells.

[Sayonara]

I'm going to call a meeting of all the other biologists and tell them AtomicMX isn't satisfied. Nobody leaves until they all agree on a definition.

 

Anyone wanna come with?

[admiral_ju00]

rofl. that should be interesting. i'm in, do it!!!!

[Duke]

Life is just a word maaaaaaaaaaan. Everythings made out of the same thing at the end of the day. Except for bluetac of course, the true origin has never been confirmed.

[YT2095]

yeah, bluetac does take a bit of explaining!

[AtomicMX]

i really dont care about what you consider a life form or not...

what i care is about definition because those definitions and concepts where made for people to understand things.... why does biologist can't build one concept... and if they found another thing to be some sort of life form.. give it another name.. like.. LifeB or Life2.... or what i know...

[Sayonara]

How about "Dark Life" or "Exotic Life"?

 

Those seemed to work out alright in physics.

i was taught that life is defined (according to science at least) by genetic material. the first form of excepted life in the evolutionary process were "Prebiologicals," and they were also the first animate matter that contained genetic material. RNA.

personally, i believe that "life" is defined by a chemical equation that we cannot see. everything in life is carried out and exists by means of a chemical equation, so "life" is just another chemical equation which humans have yet to understand.
