The book, On The Origin Of Species, " suggested " that organisms evolve through the process of natural selection. The nonrandom survival and reproductive success of randomly varying organisms
Meiosis takes place in sexual reproduction and genetic variations takes place in sexual reproduction. Genetic variations lead to evolution to new species.
The evolution of man is considered a complex process because it takes thousands of years for even a small change to occur. It is a result of genetics and physiological changes which take many generations to take hold.
Why do different organisms live in different places Why do different regions have different organisms
Survival of the species in a changing environment. A species evolves when its survival is threatened by its environment. EX: Ho-mo sapiens evolved from primitive hominids by natural selection of those hominids with the larger brains. So gradually the primates acquired larger brains and were better able to survive by out-thinking their predators, including other hominids. Ho-mo sapiens means "wise man" in Latin.

To create more genetic variability so as give momentum to the process of evolution.
Evolution is defined as the change in allele frequencies over time. Thus it has to be multi-generational, as the individuals in a single generation don't change their alleles. Similarly, individuals don't evolve (your genes don't change) and so it has to be a multi-individual process that occurs over multiple generations.
The process is called natural selection, where organisms that are best adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to the next generation.
exchange of oxygen and carbon dioxide takes place in the capillaries
Flow process takes place in open system & non-flow process takes place in closed system.
It is often believed that species evolve to become better and become an ultimate organism.This is a misconception. Evolution becomes parallel and takes place simultaneously in different species. Evolution may also be continuous mutation. Evolution takes place simply to ensure better survival in the current habitat.
