The anatomical position is defined to be the body standing upright with face and torso and feet directed forward and arms around 45 degrees away from the torso with palms facing forward. This is a standard reference in human anatomy, especially in describing body part relations (i.e. the 5th digit of the hand is medial to the umbilicus, etc.). The ulna, in anatomical position is inside or medial to the midline of the body.
<em>An easy way in determining where the ulna and the radius are is that the ulna is in line with the pinky finger and the radius is in line with the thumb. </em>
Answer:
Results in the evolution of the species: Directional selection
Results in new species: Disruptive selection
Favors traits at the two extremes: Disruptive selection
No increase in diversity: Directional selection
One extreme trait is favored: Directional selection
Diversity decreases: Stabilizing selection
Diversity increases: Disruptive selection
Explanation:
Directional selection which is also known as positive selection is known to be a mode of natural selection. In this type of selection, an extreme phenotype is favored over other phenotypes. This makes the allele frequency to move in the direction of that phenotype and this takes place over time.
Disruptive selection (known to be diversifying selection) talks about the certain changes in the population genetics whereby extreme values of a particular trait are favored over intermediate values. This results in new species.
While Stabilizing selection is a natural selection whereby there is a stabilization of the population mean on the particular value of a non-extreme trait. Here the diversity is decreases.
Answer:
Evolution
Explanation:
Whenever a species changes over a period of time, it's called Evolution, which is (normally) driven by Natural Selection.
