Genetics and Evolution

Mutation, a drive of evolution, may be a random modification in an organism’s genetic makeup that influences the population’s cistron pool. It is a modification within the nature of the DNA in one or a lot of chromosomes. Mutations bring about new alleles; thus, they’re a supply of genetic variation during a population. Recombination is […]

Introduction What is evolution? The change in the characteristics of a species over several generations is known as evolution. It is also defined as the process that leads to changes found among species or organisms observed over several generations.  Genetic Variation It means differences at chromosome levels within the members of a population and whatever

The evolutionary species concept was developed by Simpson in 1951 to include asexual organisms and extinct species because the biological species concept could not be applied. The problem arises when the evolutionary species concept was seen in the gaps in the fossil, especially the particular ones experiencing regular size or shape evolution.  Simpson’s definition of

Researchers have observed evolutionary change over time due to the evolution of genes and genomes. They have spanned research on the process of gradual change and development known as the evolutionary process. It can be defined as the adaptation process where species become compatible with a new environment or adjust themselves to new conditions. In

Introduction Today, evolution continues to puzzle the human brain. Often, individuals who disagree with the principle of evolution no longer sincerely recognise it. For example, a few humans suppose that the principle of evolution explains how lifestyles on Earth first began. The principle explains simplest how lifestyles modified after it first appeared. Some humans suppose

Biological evolution is the change in the physical characteristics of any species through several generations. Evolution depends on natural selection, which is a process of nature selecting species that are better and fit to survive compared to other species. Natural selection acts on the phenotype of a species, and the phenotype mostly depends on the

The Earth is 4.6 billion years old, and microbial life is considered to have first appeared between 3.8 and 3.9 billion years ago; in fact, microbial life accounted for 80% of Earth’s history. Microbial life is still the most common kind of life on the planet. The total number of microbial cells on Earth is

Species naturally originate through natural selection. Ecological specialization is the mechanism by which this occurs. It is defined as the evolution of reproductive isolation between populations as a result of ecologically-based divergent natural selection. The alternative mechanism is mutation-order speciation in which the population can fix different mutations as they adapt to similar selection pressures.

You’ve probably heard the phrase “It’s in my DNA” a few times and wondered what it meant. Every living organism on our planet Earth contains DNA, which is a genetic material. These structures carry the genetic instructions, which are responsible for how an organism develops, grows, reproduces, and functions from generation to generation. So, let’s

Life on Earth began billions of years ago and has continued ever since. As the environment changed, smaller and simpler organisms appeared first, and as the environment changed, simple organisms developed complex functions and evolved into complex organisms to survive in the changing climate environment. Evolution is the term used to describe this process. In
