Question:

Who is lamarck and what is he famous for? 10 points to best!!!?


pleeeeeez help. i have a test tomorrow!!!


Answers: Basically he came up with an evolution theory before Darwin...According to him acquired traits could be passed on.
Let's look at an example:
Take a girrafe...why do they have such long necks? According to Lamarack long time ago the trees started getting taller and so the girrafes had to stretch their necks to get to the leaves. This caused an extention in their necks. And the long necks were passed on by the parents to their offsprings...u gotta remember this is Lamarack theory (NOT TRUE)!!

the evolution theory we believe in today is Darwin's. AFter Lamarack Darwin started studying evolution and figured out that the long necks evolved because of a variation in species and survival of the fittest. Basically according to him, long time ago their were short-necked girrafes and long-necked girrafes but as the trees started to grow taller only the long-necked were able to survive because they could get to the leaves..

HOpe this helped!!
GOOD LUCK on the test tommorrow!! Source(s):
I did a project on this topic 2 weeks ago why not just google? Jean-Baptiste Lamarck (August 1, 1744 – December 28, 1829) was a French soldier, naturalist, academic and an early proponent of the idea that evolution occurred and proceeded in accordance with natural laws. Lamarck became interested in natural history and resolved to study medicine. Lamarck showed a particular interest for botany, and he studied the subject under Bernard de Jussieu for nearly ten years.

In 1801, he published Système des Animaux sans Vertebres, a major work on the classifications of invertebrates. In an 1802 publication, he became one of the first to use the term biology in its modern sense.
Lamarck continued his work as a premier authority on invertebrate zoology. In the modern era, Lamarck is remembered primarily for a theory of "inheritance of acquired characters", called "soft inheritance" or Lamarckism. However, his descriptions of soft inheritance were, in fact, reflections of the folk wisdom of the time, accepted by most natural historians (including Charles Darwin in his Origin of Species). Lamarck's contribution to evolutionary theory consisted of the first truly cohesive theory of evolution, in which an alchemical complexifying force drove organisms up a ladder of complexity, and a second environmental force adapted them to local environments through "use and disuse" of characteristics, differentiating them from other organisms.
