Anatomical position, or standard anatomical position, refers to the positioning of the body when it is standing upright and facing forward with each arm hanging on either side of the body, and the palms facing forward. The legs are parallel, with feet flat on the floor and facing forward.
The benefit of the palms facing forward is that it makes the radius, and ulna, the bones of the forearm run parallel to each other from the elbow to the wrist.
The term is used in medicine and related fields when referring to the position of body parts in relation to each other. There are four main anatomical positions which are:- supine, prone, right lateral recumbent, and left lateral recumbent. Each position is used in different medical circumstances.
The prone is defined as "lying flat with the face downward" and supine as "lying on the back."

<u>Answer</u>:
In an ideal intercuspal position, the mesiofacial groove of a mandibular first molar opposes "A triangular ridge of the mesiofacial cusp" of the maxillary first molar
<u>Explanation</u>:
Triangular ridges are those which arises from the cusp guidelines of premolar and molars near the central groove. Transverse ridges are designed by the grouping of two triangular ridges on the posterior teeth. The connection of the buccal and lingual triangular ridges is frequently termed as an example. Being a non-functional cusp it is a mandibular tooth. The crown touches into lingually. The cusp has four cusp edges they are mesiobuccal, distobuccal, mesiolingual and distolingual. The buccal and lingual triangular edges will lead to the establishment of the transverse edge in the central groove part.

Genetic diversity decreased as the human population migrated from Africa to other continents because each migration had a chance to obliterate one or more genetic variants.
<h3>
What is genetic diversity?</h3>
The term "genetic diversity" refers to the entire gene pool that a population or species possesses in a specific habitat.
During migration, genetic diversity is essential for adjusting to new environmental situations.
The genetic diversity decreased when the human population migrated from Africa to other continents since each migration had a chance of bringing with it one or more genetic variants.
