The inferior angle of the scapula is the bony projection that occurs bilaterally on the posterior aspect at the mid-thorax.
The inferior angle of the scapula is formed by the unification of the medial and lateral borders of the scapula. It is thick and rough and its posterior or dorsal part serves as an attachment to the Teres major muscle, to which the latissimus dorsi glides over.
The genes in a population give forth the genetic variability across a population (genotypes). In addition, occasional mutations of these genes in a population increase this genetic variability. Hovever, natural selection only favours reproduction of individuals with genes that are favourable in the environment/habitat. Therefore, natural selection has no foresight but is rather pegged on being an ‘opportunistic’ process.
Answer: the graph supports: background extinctions, mass extinctions affected the evolution of mammals and dinosaurs
The graph does not support:both mammas and dinosaur revolved in the pattern of gradualism, dinosaurs evolved by adaptive radiation, and convolution affected the evolution of mammals and dinosaurs
Explanation:The graph only shows mass extinctions and background extinctions
Answer:
The correct answer would be phenotypic variation.
Phenotype refers to observable traits or characteristics of an individual. For example, height, color, shape, et cetera.
Phenotypic variation refers to the sum total of variations in characteristics within populations of the same species.
In contrast, genotypic variation refers to the sum total of variations (such as allele frequency) present in the genome of populations of the same species.
