cum s-a creat omul

Nu putem cunoaste prea multe despre primele celule fiindca celulele nu se fosilizeaza (doh).

Ai auzit de Procariote, Eucariote sau...Metazoare ? Ce crezi, au fost descoperite fosile au ba ?

Sa-ti fie rusine in cazul asta. :cry:

Mulţumesc la fel ! :-

fitzroy a scris:

Un om de stiinta autentic insa cu siguranta nu esti.

Dacă zici tu !!! :cry:

fitzroy a scris:

Nu ai rezista mai mult de o saptamana cu modul tau de gandire intr-o institutie de cercetare de afara, indiferent de domeniu.

Poate dacă nu aş rezista afară, aş merge inăuntru ! :cry:

Doar din "deseurile" pe care le-au lasat in urma nu ne puteam da seama de prea multe.

Şi atunci de unde ştii cum a apărut viaţa ?

Dar tu de experimente de laborator in care au fost reproduse conditiile in care a aparut viata ai auzit? Si de aminoacizi creati in laborator ai auzit?

au fost reproduse conditiile in care a aparut viata ....si viata a aparut?

Tu deobicei citesti numai ce iti convine tie?Ce sunt aminoacizii? Si la ce servesc ei?

Valabil si ptr tine Lupini.

Cand cercetatorii vor crea viata (adica structuri moleculare ce se replica singure), indivizii astia vor spune "da, dar aia nu-i inteligenta". *rolleyes*

Urmatoarea relatare spune multe:

Nevertheless, even biological materialists entertained reservations; perhaps, if not plant, animal, fungal and microbial souls, some still undiscovered principle of science was needed to understand life. For example, the British physiologist J. S. Haldane (father of J.B.S. Haldane) asked in 1932:

"What intelligible account can the mechanistic theory of life give of the . . . recovery from disease and injuries? Simply none at all, except that these phenomena are so complex and strange that as yet we cannot understand them. It is exactly the same with the closely related phenomena of reproduction. We cannot by any stretch of the imagination conceive a delicate and complex mechanism which is capable, like a living organism, of reproducing itself indefinitely often."

But only a few decades later and our knowledge of immunology and molecular biology have enormously clarified these once impenetrable mysteries.

I remember very well when the molecular structure of DNA and the nature of the genetic code were first elucidated in the 1950s and 1960s, how biologists who studied whole organisms accused the new proponents of molecular biology of reductionism. ("They'll never understand even a worm with their DNA.") Of course reducing everything to a "vital force" is no less reductionism. But it is now clear that all life on Earth, every single living thing, has its genetic information encoded in its nucleic acids and employs fundamentally the same codebook to implement the hereditary instructions. We have learned how to read the code. The same few dozen organic molecules are used over and over again in biology for the widest variety of functions.

eu citesc ce spui..... iar aminoacizi sunt substante chimice..... dar pina sa apara au alte reactii ? nu de alta dar sa nu spui ca asta e viata ca te faci singura de ras.......

multa iubire

Za lisanar, vezi ca te faci tu de ras... mai bine pune mana si citeste despre aminoacizi si cum se combina si ce rezulta din combinarea lor.
