Lamarck’s theory seems to be in agreement with the Darwinian Theory which states that evolution produces life forms adapted to their environments. However, Lamarck argued that the organism itself can control the direction of change whereas Darwin did not agree with that postulate. “For a long time it was mistakenly thought that evolution was a simple linear progression, with humankind at the top of the ladder. We now understand that evolution proceeds with species on one branch giving rise to other branches and so on” (What is evolution?, n. d). We have lot of animals in this world which like the leaves in big trees. For example, elephants, cattle etc like the leaves of some big trees. However, these animals do not have such a big neck like the giraffes. These animals also should have tried a lot in the past to reach out the higher branches of the trees. But they never got their neck extended just like giraffes. ...

On the other hand, other analysts argue that, evolution can be justified on a scientific ground, a fact that explains that evolution is a theme that can be discussed with a lot of evidential support on focus. Buss (2004, pp.25) indicates that, if a theory is shore up by a lot of persons, it is bound to outweigh all the flaws that might be imposed on the theme.
According to Heinrich, before agricultural evolution, humans spread throughout the globe, Therefore surviving in the different habitats did not only depend on the specific genetic configuration, but depended also on large body of cultural information transmitted across the groups, abilities, and other skills that no human could have comprehended alone.
Lines are often drawn along religious beliefs that reject the theory of evolution, while other camps argue that the theory is fact. Evolution is often misunderstood and has challenged scientists to provide proof for the belief that all life transforms, progresses, and adapts to its environment.

he term used to refer to the process where inherited traits in a species change from generation to generation resulting in variations, which accumulate over a long period of time causing new species to emerge. According to scientists, macroevolution entails variation,
Adaptations are produced by natural selection and are well-fitted to their function. Many forms can be taken by adaptation, for example, an anatomical feature that allows the organism to access a new and valuable resource, a protein that

In nature, biological organisms have many off springs as compared to their chances of surviving. If it were goal directed then all the off springs would have equal chances of surviving so as they can live to evolve (Lenomard, Roze & Rousset, 1919).Evolution also
