Answer:
Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.
But Evolution is not True See this Article
How Did Life Get Its Start?
The DNA structure
WHAT SOME SAY. Life arose spontaneously from nonliving matter.
WHY SOME PEOPLE ARE NOT SATISFIED WITH THAT ANSWER. Scientists know more about the chemistry and molecular structure of life than ever before, yet they still cannot define with certainty just what life is. A wide gulf separates nonliving matter from even the simplest living cell.
Scientists can only speculate about what conditions on earth were like billions of years ago. They have differing views about where life began—for instance, whether within a volcano or under the ocean floor. Another belief is that life’s building blocks first formed elsewhere in the universe and arrived here embedded in meteors. But that does not answer the question of how life began; it just pushes the issue from earth into space.
Scientists speculate about the existence of molecules that preceded genetic material as we know it today. These molecules are supposedly more likely to arise spontaneously from inert material and are self-replicating. Yet, science has found no evidence that such molecules ever existed, nor have scientists been able to create any such molecule in a laboratory.
Living things are unique in the way they store and process information. Cells convey, interpret, and carry out instructions contained within their genetic code. Some scientists liken the genetic code to computer software and the chemical structure of the cell to computer hardware. But evolution cannot explain the source of the information.
Protein molecules are necessary for the function of a cell. A typical protein molecule consists of hundreds of amino acids strung together in a specific sequence. Additionally, the protein molecule must fold into a specific three-dimensional shape for it to be useful. Some scientists conclude that the probability of even one protein molecule forming spontaneously is extremely low. “Since a functioning cell requires thousands of different proteins,” writes physicist Paul Davies, “it is not credible to suppose they formed by chance alone.”
CONCLUSION. After decades of research in virtually all branches of science, the fact remains that life comes only from preexisting life.
How Did Living Things Develop?
A chameleon that matches the color of a leafy branch
WHAT SOME SAY. The first living organism gradually developed into a variety of living things, including humans, through a process of random mutation and natural selection.
