How are Lamarck Jean-Baptiste Pierre Antoine de Monet, chevalier de Lamarck, often known simply as Lamarck, was a French naturalist. He was a soldier, biologist, and academic, and an early proponent of the idea that biological evolution occurred and proceeded in accordance with natural laws.Jean-Baptiste Lamarck
What theory did Lamarck propose?
Lamarckism or Lamarck Theory is called the scientific theory on the evolution of species, proposed by the French naturalist Jean-Baptiste Lamarck in his book Zoological philosophy of 1809. This is the first evolutionary theory in history, fundamental predecessor of the one later proposed by Charles Darwin in 1859.
Is evolution a theory, a fact, or a law?
Evolution, in this context, is both a fact and a theory. It is an incontrovertible fact that organisms have changed, or evolved, during the history of life on Earth. And biologists have identified and investigated mechanisms that can explain the major patterns of change.
Who developed the modern theory of evolution?
When it comes to the evolution of life, various philosophers and scientists, including an eighteenth-century English doctor named Erasmus Darwin, proposed different aspects of what later would become evolutionary theory. But evolution did not reach the status of being a scientific theory until Darwin’s grandson, the more famous Charles Darwin, published his famous book On the Origin of Species.
What is the law of natural selection?
What is the law of natural selection? Abstract. The fitness of a population is defined to be a real smooth function of its environment and phenotype. Darwin’s law of natural selection implies that a population in equilibrium with its environment under natural selection will have a phenotype which maximizes the fitness locally.

What is the demand for variation among species by nature?
The demand for the existence of variation among species by the nature could be well explained through his theory. According to Ecology, there are available niches in ecosystems that species (animals, plants, and all other species) have to adapt in order to survive.
