What theory of evolution did lamarck develop in 1809?
Jean Lamarck's theory of evolution is known as zoological philosophy or the inheritance of acquired characteristics, and stated that changes to an organisms phenotype (basically what it looks like) will cause changes to it's genotype (DNA). This has been disproved of by modern scientists, with natural selection as the main theory.
Which statement is not included as a part of the modern theory of evolution?
sexual reproduction and mutations provide variation among species
What did LaMarck do?
Jean-Baptiste LaMarck's evolution theories included soft inheritance, Lamarckism. The idea that an organism can pass on characteristics it acquired during it's lifetime onto it's offspring, a use/disuse theory(i.e., burrowing animals such as a mole now have small eyes due to disuse). In 1801, he published a major work in the classification of invertebrates, a term he coined. In 1802, he was one of the first scientists to use the term biology in modern sense.
What is Lamarck's theory of evolution by natural selection?
Lamarck's idea of how evolution works was through inheritance of acquired characteristics which stated that offspring get the modifications acquired by parents. Further, he believed in "use and disuse", which stated that using a part of the body will make it bigger and stronger, while disuse will make it smaller (such as appendix). Of course, these ideas were strongly rejected in favor of natural selection.
How did Darwin influence modern views of evolution?
how has Charles Darwin influenced people about modern views of evolution
What is meant by modern theory of evolution?
The term 'modern theory of evolution' most likely refers to the 'modern synthesis', which combines Darwin's classical model with modern genetics.
How was the 'Starry Night' acquired?
It was bequeathed to the Museum of Modern Art in1931 by Lillie P Bliss, who had acquired a large collection of modern paintings.
Are there any evolution of inventions till modern times?
YES,THERE HAS BEEN MANY EVOLUTION OF INVENTIONS TILL MODERN TIMES.
What did Lamarck's idea of the inheritance of acquired traits propose?
First of all, Lamarck's theory of evolution of new species was wrong (disproved by various experiments). It stated that new species emerged by the use and disuse of organs. This, he called The Theory of Acquired Inheritance.For example, the ancestors of Giraffes found that all lower leaves on the trees were exhausted. So they started stretching their necks to reach higher leaves. Over the course of evolution, their neck length increased and thereby gave rise to modern day giraffes.Another similar example would be that of snakes. The ancestors of snakes had limbs. But they 'disused' the limbs and over the course of evolution, snakes emerged by the loss of limbs.Its worthy to remember that only the DNA in germ cells is inherited to the offspring and not that of somatic cells. So lamarckism is basically wrong because the changes in organs cannot be inherited by the offspring.Hope this helps.
Why are only inherited traits not acquired ones involed in the process of natural selection?
Because the idea of acquired traits states that simple organisms could arise from nonliving matter and could form complex forms of living, which is not supported anymore by modern scientific study of mechanisms of inheritance.

The term 'modern theory of evolution' most likely refers to the 'modern synthesis', which combines Darwin's classical model with modern genetics.
