Ardipthecus ramidus can be described as:
(D) lack of a canine diastema.
What is canine diastema?
Canine diastema is a void or opening between the canine and teeth next to it. It enables the upper and lower teeth to bite together by making room for the point of the opposing canine tooth that is projecting.
An australopithecine species called Ardipithecus ramidus lived 4.4 million years ago in the Afar area of Early Pliocene Ethiopia. Ramidus, as opposed to modern hominids, has evolved for both life in the trees (arboreality) and walking on two legs (bipedality).
This species could travel on all four limbs in trees and was a facultative biped that stood erect on the ground. The anatomy has very basic characteristics. Upper canines are evolved from Australopithecus afarensis and have a diamond form as opposed to the pointed shape seen in African apes.
The discovery of Ardipithecus closes one of the last significant gaps in the history of humanity. It demonstrates that the last animal that humans and chimpanzees had in common was not even biologically similar to chimps.

discuss how the discovery of homeotic genes and developmental bias challenge the traditional views of the modern synthesis.
These homeotic genes are ordered on the DNA in the same way that they are expressed along the body axis during development.
The discovery of the genes that govern embryonic development was made possible by a little monster: a fruit fly (Drosophila) with an additional set of wings.
The evolutionary significance of developmental limitation has long been debated. Constrained advocates have been skeptical of what they regard as neo-Darwinians' panselectionist approach.
However, such supporters have been chastised for taking an overly simplistic view of Neo-Darwinism. Some argue that neo-Darwinian theory includes developmental constraints.
Two factors have limited progress in determining the evolutionary function of developmental constraints: terminological issues and a lack of clear, unambiguous instances.
I address both of these concerns in this article. I provide definitions that correspond to the majority of prior usage, but not all.
I then discuss the example of centipede segment number constraint, which is particularly clear in that an alternative selective explanation for the observed pattern of character states is highly implausible.

c.The voltage-gated sodium and potassium channels both remain closed.
d.The sodium channel opens, and Na+ ions flow out.
The sodium channel opens, and Na+ ions flow in is the correct behavior observed when the voltage across a neuronal membrane is -20 mV.
The stable state of the cell is referred to as the "resting membrane potential," which is a dynamic process that balances ions that leak down their concentration gradient and ions that are pushed back up their concentration gradient. The resting membrane potential will remain unchanged regardless of external factors.
When a voltage across a neuronal membrane is set to -20 mV, this facilitates the opening of voltage-gated sodium channels in the neuronal membrane. This is because the concentration of Na+ is higher outside than inside the cell.
Therefore, the ions will rush into the cell by chemical and electrical gradients. As the sodium ions keep entering the cell, it will cause the membrane less negative. This process is known as depolarization.
