What are at least three differences between apes and humans in the cranium and teeth?

Biology

Mama L [17]3 years ago

 The following are key characteristics of ape skulls that human skulls do not have:

(1) Prognathic Jaws: A chimpanzee’s maxilla (upper jaw) and mandible (lower jaw) protrude significantly. Typically, the bone from the nose to the tip of upper teeth extrudes out at about a 45 degree angle, whereas a line drawn from the nose to the chin of a typical human is vertical or concave.

(2) Large Brow Ridges above the eye sockets. Humans have negligible brow ridges.

(3) Absent or small laid back forehead: Apes lack significant vertical foreheads. Humans have large vertical foreheads, which provide room for the much larger frontal lobeof our brains. This is an important difference, as the large frontal lobe of the human brain allows us the ability to make decisions and solve problems. It also controls our behaviors, voluntary movements, emotions, and consciousness. Without a forehead, an animal would not have room for a large frontal lobe, and could not perform functions that differentiate animals from humans. The ability to make tools, improve on them, and the ability to remember how to make them, wouldn’t be possible without a forehead and large frontal lobe.

(4) Small Ovoid or Flat Cranium that houses their much smaller brains. Human adult craniums are about two to three times the volume of ape craniums. Ape craniums are narrower than the lateral extents of the eye sockets, whilst human craniums are far wider then the outer extend of their eye sockets.

What is true concerning a quantitative trait? Multiple Choice Individuals fall into distinct classes for comparison The phenotyp
lana66690 [7]

Answer:

The phenotypic variation for the trait is continuous

Explanation:

Genetically speaking, quantitative traits are controlled by many genes, classes are not easily distinguishable and there is a continuous distribution of the phenotype. These characteristics refer to measurements of quantities (weights, volumes, measurements: kg, m, cm, g, m2, etc.).

In other words, quantitative characteristics are those that exhibit continuous variations and are partly of non-genetic origin; that is, they are greatly affected by the environment.

One of the reasons for this is that our unconscious handwriting incorporates into it different mental, physical, and mechanical
Liula [17]

Answer:

The correct answer is: True.

Explanation:

  • The writing of a person is controlled by an region located in the left part of frontal lobe of the brain which is known as the Broca's area.
  • Writing is a motor impulse send by the brain to the hand and fingers.
  • However, no two individual can have the same hand-writing.
  • This is because hand-writing is not only dependent on the brain to hand motor co-ordination.
  • It also depends upon the psychology, mentality, thought process, state of mind, nature of the person and also the influence of the surroundings on the person.
  • It also depends on the preference of the person to keep his writing artistic or simple or illegible.
  • All these factors can never match between two persons.
  • This is the reason, no two persons can share the exactly same hand-writing.
