First, there are usually intensified reactions to death or loss. For example, the griever may become more depressed or angry due to not being able to fully express his or her grief. Secondly, disenfranchised grief means society does not recognize the death or loss; therefore, the griever does not receive strong social support and may be isolated.
Ambiguous loss is a loss that occurs without a significant likelihood of reaching emotional closure or a clear understanding. [1] [2] This kind of loss leaves a person searching for answers, and thus complicates and delays the process of grieving, and often results in unresolved grief.
Developmental psychobiology posed this question since the lack of knowledge about the precise coordination of all cells, even those not related anatomically, in space and time during the embryonic period does not allow us to understand what forces at the cellular level coordinate four very general classes of tissue deformation, namely: tissue ...
Grief is the response to the loss of something deemed important, particularly to the death of a person or other living thing to which a bond or affection was formed. Although conventionally focused on the emotional response to loss, grief also has physical, cognitive, behavioral, social, cultural, spiritual and philosophical dimensions.

Neutral mutation has become a part of the neutral theory of molecular evolution, proposed in the 1960s. This theory suggests that neutral mutations are responsible for a large portion of DNA sequence changes in a species. For example, bovine and human insulin, while differing in amino acid sequence are still able to perform the same function ...
Population bottleneck followed by recovery or extinction. A population bottleneck or genetic bottleneck is a sharp reduction in the size of a population due to environmental events such as famines, earthquakes, floods, fires, disease, and droughts; or human activities such as genocide, speciocide, widespread violence or intentional culling.
Incomplete lineage sorting (ILS) [1] [2] [3] (also referred to as hemiplasy, deep coalescence, retention of ancestral polymorphism, or trans-species polymorphism) is a phenomenon in evolutionary biology and population genetics that results in discordance between species and gene trees.
