According to the field of biology, what explains the variety of reproductive and survival strategies that have appeared and disappeared from living organisms (past and present) since the origin of life on earth? Modern evolutionary synthesis Natural selection Adaptation Sexual selection Gene pool Scientific theory Resources Red Queen hypothesi:s Non-random mating - Fitness Allele frequency MutatiornExplanation / Answer
Evolution basically means development which is a slow stage process that depends on adaptation to different environments. If an organism is adapting to a new environment then it will be reflected in its genes and that is passed on to its generations.
We have evolved from bacteria, which is because of evolutionary changes that resulted billions of years ago. Each and every organism of the Earth is interconnected and thats why we have such huge biodiversity.
Changes are continuously happening to evolve better and better. So, environmental factors or resources play a major role in evolution.
Natural selection is based on the fact that individuals which can survive and reproduce at any given environment is the most fit. Hence, all the individuals in a population selected by natural selection will be most fit which can pass on its traits to next generation to increase the population size.
Natural selection does not reduce the fitness of a population which in turn increases the fitness of an individual in a population.
Adaptation to new environment or to any given environment, the changes need to be at the genetic level where mutation occurs. A change or mutation brings about a new trait which can adapt to new environment. Hence, natural selection preserves that trait or genetic variation by selecting that best fit individual from other non-adaptable traits. And, it can directly means that it preserves more genetic variation or traits which are called survival of the fittest.
There are many scientifc theories that explains about the process of evolution. Red Queen hypothesis explains about the importance of genetic diversity which results from sexual reproduction and an organism need to adapt at any given environment to survive among other organisms.
Modern evolutionary synthesis merged the Darwin's evolution theory and Mendelian genetics. Based on the new hypothesis as a result fusion, evolution is defined as changes in allele frequency of gene pool of any given population.
Therfore, evolution depends on the following process to result in genetic diversity or biodiversity,
