Question

difference between heridity and evolution



in brief
​

Answer 1

Answer:

Heredity: The passing of traits from the parents to offspring is called heredity. This is heredity which is responsible for many commonly observable facts; like siblings looking similar in overall appearance.

Evolution: The change in inherited traits in biological population over subsequent generations is called evolution. Scientists have proven that life evolved in the form of simple unicellular organisms on this earth; and all the organisms which are present today have evolved from a common ancestor. The idea of evolution is based on the premise of a common ancestry.

Answer 2

Explanation:

In the simplest of words, heredity refers to the passing of traits or characteristics through genes from one generation (parent) to the other generation (offspring). Heredity is very evidently seen in sexual reproduction. This is because, in this process, the variation of inherited characteristics is high.

The variation occurs due to some errors in DNA copying. Variation is important because it contributes to the evolution and forms the basis of heredity. Variation is caused due to gene mutations, the interaction of genes with the environment, and various combinations of genetic material. Remember that variation can occur through the asexual reproduction process too. But, these variations are not very noticeable.

evolution

There is a lot of science behind the theory of evolution. Scientists and researchers have done intensive studies to show how living things evolved and how traits and characteristics passed on from generations to generations.

Ultimately, when we speak of evolution, we actually speak of the genetic characteristics that are inherited and passed on from one generation to the other

An important basis on which the theory of evolution is based on is that all species are related and gradually change over time. But the frequency of an inherited trait that undergoes a change is spread over generations. Genes control the traits. Therefore we can say that the frequency of genes in a population changes over generations.
