The living matter shows attributes or characters like responsiveness, growth, metabolism, energy transformations and reproduction
Definition: Adaptive radiation refers to the evolutionary process where diverse species emerge from a common ancestor and spread out in various directions.e.g 1. Darwin’s finches on the Galapagos Islands exemplify adaptive radiation, originating from a single seed-eating species that arrived by chance. 2. The diverse beak shapes in these finches evolved as a result of … Read more
Speciation refers to the evolutionary process wherein a single species diverges into two or more genetically distinct entities, often influenced by factors such as genetic drift, migration, geographical isolation, and natural selection.
Population refers to the aggregate count of individuals residing in a specific region during a given timeframe. It encapsulates the total number of people present in a particular area at a designated moment. Essentially, population represents the collective populace within a defined temporal and spatial context.
Organic evolution is the phenomenon where alterations in the genetic makeup of organism populations take place as a response to shifts in the environment.
Gene frequency, as defined by Gillespie (2004), represents the proportion or percentage of a population possessing a specific allele at a given genetic locus. This concept is more accurately termed allele frequency. It quantifies the prevalence of a particular gene variant within a population, reflecting the distribution of alleles at that locus.
The gene pool encompasses the entirety of genes within a breeding population, constituting the genetic information for a specific species. It serves as the fundamental level for evolutionary processes, as variations in the gene pool contribute to the emergence of new species.
