The reason that evolution takes a long time is because each generation, the offspring are nearly identical to their parents. However, they are slightly different, and thus a few of the individuals are slightly more likely to survive than the others. Then, these individuals spread their genes to just a few more offspring than the others do.
Because there is only a tiny difference in how many offspring the more adapted version has, it takes a long time for the more adapted version to completely replace the older version.

How long does the process of natural selection and evolution take?
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.
How long did the evolution take?
The process of evolution has been ongoing for billions of years, with life forms gradually changing and adapting to their environments over time. The exact duration can vary depending on the specific species or traits being considered.
When and where does evolution take place?
Evolution takes place over long periods of time in natural populations in various environments around the world. It occurs through genetic changes in populations over generations, resulting in the accumulation of adaptations that enhance survival and reproduction.
As a group the large scale evolutionary changes that take place over long periods of time are called?
These large scale evolutionary changes that take place over long periods of time are called macroevolution. It involves the evolution of species over geological time scales, leading to the formation of new species and higher taxonomic groups.
What is the slow change in the genetic composition of a whole species over a long period?
The slow change in the genetic composition of a whole species over a long period of time is called evolution. This process occurs through mechanisms such as natural selection, genetic drift, and mutation, resulting in the gradual accumulation of changes in the heritable traits of a population.
Why would evolution take 4.2 billion years?
Evolution doesn't take 4.2 billion years. It takes forever and no time at all. Where life is, there evolution is happening, and it will continue to happen as long as life exists.
How long did it take for evolution?
To see evolution it take hundred thousand, or tenth of thousand.
In biology evolution means what?
Evolution in Biology terms means a change in a species over a long period of time. It can take several generations for a characteristic in a species to change.
What effect does generation time have on evolution?
A long generation time makes for a slow evolution rate, and a short generation time makes for a fast evolution rate.
How long did it take for it?
To see evolution it take hundred thousand, or tenth of thousand.
How long does evolution take?
Forever really, its an ongoing process
What are organisms that change over long periods of time?
Evolution
What is the main factor that effects the evolution of a star?
The mass of the star affects the evolution of the star. It helps to determine how long evolution will take and what kinds of changes will happen.

The gradual change in living things over long periods of time is called?
The gradual change in the characteristics of a species over time is called evolution. The theory of evolution by natural selection was first proposed by Charles Darwin.
What do scientists call the change in species over long periods of time?
Evolution is the change in species over long periods of time.
