what are they key point in darwinism ,neo darwinism, lamarkism sso above theory can be differentiated..
i m mixing dem :(
anny idea ?
Do you know what any of the three on the list are?
yea they are the hypothesis which are rejected on organic revolution
Yes. I meant, do you know in specific what any of these are? The question is a little ambiguous. It didn't ask about the theories themselves, it asked about "-isms" which, depending on your definition, may or may not include the social movements and changes in thought sparked by the scientific theories.
ok one by one i m explaining each help me to find out the key point ok ??
lamarkism: he said that the organism which used the organ mot dat organ get developed and the organ which is used in less are getting reduced generation by generation and become extinct
Indeed it does. Darwinism and neo-darwinism are closely related. Darwinism is basically natural selection applied to observable traits. And neo-darwinism is darwinism applied to natural selection of genes. At the genetic and molecular level.
noelamarkism in thi i m haaving prob :( can u xplain me?
I don't think there is a neo-lamarkism...
neo lamarkism termed by pakard
Ah, my bad, there is.
yea there is neolamarkism modification of lamarkism and and noe darwinism is the modification of darwinism and i m ahving trouble in both neo :(
OK. Darwinism basically says that traits which make an animal poorly adapted to its environment mean that it will be less successful passing on its genetic material so those disadvantageous traits become less common. Natural selection. Neo-Darwinism is just the molecular version of that. Alleles or gene variants less advantageous will make the organism less successful in passing on its genetic material. So those alleles will become less common. Darwinism deals with traits at the phenotypic level, Neo-Darwinism deals specifically with traits at the genotypic level.
hey i also heard that darwin dont have a knowledge of genetics is it truee??
Depends on what you mean by "knowledge of genetics." He certainly understood that there was some way organisms pass info from parents to offspring, but he saw it as just that: information passing. He did not know about genes. Darwin published in 1860 or so. Mendel did his experiments on pea plants from 1860-1870 or so and it was basically ignored for another 10-15 years because no one was interested in it. The ideas of genetics, genes, alleles, all that came about 25 years *after* Darwin published the Origin of Species.
yea right.. and wbu neolamarkism?
Neo-Lamarckism has to do with Lamarckian ideas applied to behaviour. Lamarckism has to do with physical traits only.
ok thnx :)
