The key difference between directional and disruptive selection is that the directional selection prefers and selects only one extreme trait among the two extreme traits whereas the disruptive selection favours both extreme traits together. The theories of directional and disruptive selection came into limelight with the introduction of the theory of Natural Selection by Charles […]
Difference Between Chemical and Organic Evolution
The key difference between chemical and organic evolution is that the chemical evolution occurs due to changes in the structure of the molecules; from complex molecules to simple molecules with the passage of time whereas the organic evolution occurs due to the changes in the genetic composition of populations of organisms in response to environmental […]
Difference Between Synapomorphy and Symplesiomorphy
Key Difference – Synapomorphy vs Symplesiomorphy Evolution is considered as the change in heritable characteristics of different biological populations over time and the successive generations. It is an important aspect that develops the diversity of different biological systems. It also helps to trace and identify common ancestors from whom these organisms descendent. Synapomorphy and […]
Difference Between Paranthropus and Australopithecus
Key Difference – Paranthropus vs Australopithecus Hominidae is a taxonomic family of primates whose members are known as great apes or hominids. This taxonomic group included the ancient extinct hominins such as Paranthropus, Australopithecus and Homo group including modern man. The Paranthropus is described as a genus of extinct hominins. They were also known […]
Difference Between Gradualism and Punctuated Equilibrium
Key Difference – Gradualism vs Punctuated Equilibrium Evolution and the process of species evolution are based upon the changes that take place in a population over a period of time. There are many theories put forward by scientists, geologists, and philosophers on the theory of evolution. Considering all the available theories, scientists have accepted […]
Difference Between Lamarckism and Darwinism
Key Difference – Lamarckism vs Darwinism Evolution is defined as the heritable changes occurring in a population over a particular time period. Through the course of time, different theories have been put forward to explain the evolutionary mechanisms of organisms. Lamarckism and Darwinism are two such theories put forward. Lamarckism is based on the […]
Difference Between Early Man and Modern Man
The key difference between early man and modern man is that the term early man refers to the prehistoric hominids who are the forefathers of the current figure of the human race while the modern man refers to a subspecies of Homo sapiens. Early man and modern man are easily distinguishable from each other from […]
Difference Between Microevolution and Macroevolution
The key difference between microevolution and macroevolution is that the microevolution includes small-scale evolutionary changes especially within a single species population while the macroevolution includes large-scale evolutionary changes that lie beyond the boundaries of single species population over a longer period. Evolution is a natural process that takes place on its own over a long […]
