B. Many small changes can eventually make a species very different.
Evolution by natural selection actually relies on variation within a population. Without variation, there would be no genetic differences for natural selection to act upon, leading to no evolution. Variation provides the raw material for natural selection to work with, allowing beneficial traits to be favored and passed on to future generations.
Success in terms of evolution by natural selection is typically measured by an organism's ability to survive and reproduce in its environment. Traits that enhance an organism's chances of survival and reproduction are favored by natural selection, leading to their increased frequency in a population over generations. Ultimately, success in evolution is defined by passing on genetic material to future generations.
The change in details of the body plan and functions of organisms through generations is known as evolution. This process occurs over time through genetic variation, natural selection, and other mechanisms, leading to the development of new species with different characteristics.
The process of natural selection and evolution can vary in terms of the time it takes, ranging from hundreds to millions of years depending on the species and environmental factors. Evolution is a gradual process that occurs over generations as populations adapt to their changing surroundings through natural selection.
Biological evolution refers to the change in inherited traits over generations in populations. Stages of biological evolution could refer to processes within evolution, such as variation, selection, and inheritance, that contribute to the overall evolutionary change in a population.
New generations are better suited to survive than previous generations.
Natural selection is the process by which certain traits that provide a reproductive advantage become more common in a population over time, leading to evolutionary change. Evolution is the overall change in a population's genetic makeup over successive generations, driven by mechanisms such as natural selection. In essence, natural selection is one of the primary mechanisms through which evolution occurs.

The process of natural selection and evolution can vary in terms of the time it takes, ranging from hundreds to millions of years depending on the species and environmental factors. Evolution is a gradual process that occurs over generations as populations adapt to their changing surroundings through natural selection.
According to evolutionary theory, natural selection is the principle that directs evolution.
The smallest unit that can evolve is the population, not the individual. In other words, you can't evolve, but over generations, the population can be subject to natural selection and different traits can be selected. In addition, the evolution of a population will take generations of fluctuating gene frequencies, something you can't just watch in action. Of course, the speed of evolution is entirely dependent on the environment; some populations will evolve quicker than others.
Biological evolution refers to the change in inherited traits over generations in populations. Stages of biological evolution could refer to processes within evolution, such as variation, selection, and inheritance, that contribute to the overall evolutionary change in a population.
In the science, evolution means change over time. These changes are selected by the environment. What genes (traits) that will allow a species to survive will be passed on to the next generations.
Natural selection is a key mechanism in evolution where organisms with advantageous traits are more likely to survive and reproduce, passing on those traits to future generations. This process leads to the gradual change and adaptation of species over time.
