The theory of evolution can be defined as the idea that species change over time through natural processes. It is the scientific explanation for the diversity of life on Earth.
According to this theory, all living organisms share a common ancestry and have gradually evolved into different species over millions of years.
Evolution is driven by natural processes such as genetic variation, mutation, natural selection, and genetic drift. These processes lead to changes in the inherited traits of organisms over generations.
Contrary to the belief that all species were created in their current form, the theory of evolution proposes that species evolve through a gradual process.
It is not a hypothesis that organisms strive to improve themselves over generations, as evolution does not have a goal or direction. Instead, it is a process that occurs due to factors such as environmental changes and the pressures of survival and reproduction.
Evolution does not occur through a series of sudden and dramatic changes, as stated in the fourth option. Rather, it is a slow and continuous process that happens over long periods of time. In summary, the theory of evolution is the concept that species change over time through natural processes.
It is supported by extensive scientific evidence from various fields of study, such as paleontology, genetics, and comparative anatomy.
