More Evidence of Evolution

Introduction

Charles Darwin, who is also called the father of evolution, shows the evidence of the evolution of an organism after millions of years depending on the earth. In the 19th century, biologists studied more than 20 years of his life regarding the fossils of extinct animals found in different places of the earth. 

Darwin was a very fine experimentalist and observer, he observed flowers and animals and their pattern of existence. As time goes Darwin’s sources of evidence have become more comprehensive and throws recent genetic biochemistry, physiology, ecology, animal behaviour, and Molecular Biology type of studies to evolve. 

The evidence of Evolution charts generally depends upon an organism’s genetic variation, which helps them challenge and tackle natural selection.

Darwin’s theory and research help get a large amount of information about evolutionary history stored in DNA evolution by relying on DNA genetic variation where the physical characteristics of an organism are affected. Then they can be passed on to their offspring.

The primary evidence showing evolution throughout the years depends on the critical points of anatomy, Molecular Biology, biography, fossils, and direct observation. 

Darwin also dedicated the book called on the origin of species to identify the patterns of nature constituent with the evolution so that the understanding becomes more evident. 

Fossil

The most important physical evidence which allows the study of evidence of evolution is called the fossil. Fossils are obtained by digging soil, they are preserved remains of organisms that lived past geological age. For example bones, shells, stone imprints, oil, coal and DNA all are evident proof of the evolution of the earth through time. The study of fossils is called Palaeontology. A palaeontological studies the bones for the age of formation, the evolutionary significance.  

Fossils are known for recording the past information of intermediate species. These fossils provide a great deal of knowledge and information about the environment, features and characteristics of the ancient organism. The scientists determine the age of fossils and then categorise them from the year the organism lived relative to other organisms similar to it.

The fossils tell the story of the past Evolutions and show the evolution from thousands of millions of years. 

The Evolution of the Organism

The adaptation of the organisms to survive in the changing environment is called evolution. Evolution in organisms can be reflected through genes, noble traits, and new species. The evolution of an organism is dependent on two major factors –genetic variability and change in geographic location over time. The anatomy is another type of evidence found in the organism structures that evolution made them change, for example, in the bones of humans, dogs, and other organisms. There are four types of evolution: divergent evolution, convergent evolution, parallel evolution and coevolution. The mechanisms through which the characteristic evolution happens in organisms are mutation, genetic drift, gene flow, non-random mating, population speciation and natural selection. 

Over time, the revolution has led to changes in the shape and size of the human bones of different species to maintain natural selection. The overall layout scientist calls these the interchangeable parts homologous structures. 

Due to some evolving functions, some organs do not have much work; therefore, they get diminished and appear to be as a schedule apart from the common past and sisters; these structures are also called vestigial structures. There are also many types of biological evidence such as by the uses of biogeography and molecular biology it can be seen that the evolution follows a pattern after millions of years the theory of evolution shows that the patterns of species do not overtime or in the Fossil record but also depends on the distribution of species today around the earth. Marsupials of Australia, the finches of the Galapagos, are unique species that have evolved from their ancestors on the mainland. 

Molecular Biology

Molecular biology shows the anatomical structures of the molecule (that is, the DNA) with modifications that got passed on from the ancestors to their offspring. The versatility of DNA being genetic material found in all organisms shows evidence of common types of ancestral origins. At the most basic level, most living organisms share the same genetic material and genetic codes, therefore also sharing the basic process of gene expressions and molecular building blocks, which are called amino acids. 

There are many misconceptions regarding the theories of evolution. However, there are many controversies while these pieces of evidence were first proposed.

After the publication of the ‘origin of species,’ Darwin’s research was almost universally accepted by biologists, particularly the young biologists worldwide. However, some misconceptions remain, such as evolution just being a theory on organisms evolving on purpose and evolution not explaining the origin of life.

Conclusion 

Almost 3.5 years ago, the diversity of today’s life was a path that was laid from the origin called life. With his work on the ‘origin of species, utilising natural selection, Charles Darwin showed the world about different theories of evolution and made them aware of their ancestors or primitive origins. The anatomical structures of the molecule (that is, the DNA) with modifications that got passed on from the ancestors to their offspring is shown through molecular biology. Fossils are known for recording the past information of intermediate species. These fossils provide a great deal of knowledge and information about the environment, features and characteristics of the ancient organism. The scientists determine the age of fossils and then categorise them from the year the organism lived relative to other organisms similar to it.

The evolution is various types of plants and animals and other living human beings and organisms that have inherited different characteristics and study their anatomy and ancient ecology.
