Lowest common a common ancestor. Medical search. Frequent questions

Groups of males with the same surname so tested and compared can define family groups and establish a probability they have a most recent common ancestor within the time frame that surnames were adopted in Western Europe (about the 13th and 14th centuries). (familytreedna.com)
Genealogical research combined with Y-DNA testing can often determine and verify a most recent common ancestor of a group of males who have been found to be related. (familytreedna.com)
Details of each of the steps involved are presented, including reference-based assembly, identification of SNPs relative to the reference, filtering of SNPS, mapping the high-quality SNPs on to a phylogenetic tree, and determining placement of the most recent common ancestor. (cdc.gov)

Computation of lowest common ancestors may be useful, for instance, as part of a procedure for determining the distance between pairs of nodes in a tree: the distance from v to w can be computed as the distance from the root to v, plus the distance from the root to w, minus twice the distance from the root to their lowest common ancestor (Djidjev, Pantziou & Zaroliagis 1991). (wikipedia.org)
Tarjan also found a simpler but less efficient algorithm, based on the union-find data structure, for computing lowest common ancestors of an offline batch of pairs of nodes. (wikipedia.org)
Find the lowest common ancestor (LCA) of the two nodes. (hackingnote.com)
The lowest common ancestor is the node with largest depth which is the ancestor of both nodes. (hackingnote.com)
Given two nodes in a binary tree, write a function to find the lowest common ancestor. (byte-by-byte.com)
According to the definition of LCA on Wikipedia: "The lowest common ancestor is defined between two nodes v and w as the lowest node in T that has both v and w as descendants (where we allow a node to be a descendant of itself). (zhaoshuaijiang.com)
For example, the lowest common ancestor (LCA) of nodes 5 and 1 is 3. (zhaoshuaijiang.com)

In a tree data structure where each node points to its parent, the lowest common ancestor can be easily determined by finding the first intersection of the paths from v and w to the root. (wikipedia.org)
If neither, it means that the current root node is the smallest common parent node and return directly. (leetcode.ca)
From the another node, find the common node among previously found ancestors from that node to the root. (tkhwang.me)
Each internal node is labeled with the common prefix of the values in its subtree and typically, the left child adds a 0 to the end of the prefix, while the right child adds a 1. (wikipedia.org)
This is the node in the trie that has the longest common prefix with k . (wikipedia.org)
If a node with that prefix does exist, A k can not be at a higher level, so we restrict our search to the current and lower levels. (wikipedia.org)

East Africa is famously the birthplace of humankind and the location where our ancient hominin ancestors first invented sophisticated stone tools. (cosmosmagazine.com)
This suggests that human ancestors spread to the region much earlier than previously thought or that the stone tool technology was simultaneously invented by earlier hominin species living outside east Africa. (cosmosmagazine.com)
There have been discoveries of early hominin sites to the south, in Chad , that suggest that some of our earliest ancestors lived well beyond East Africa. (cosmosmagazine.com)

Sickle-cell anaemia is particularly common among people whose ancestors come from sub-Saharan Africa, India, Saudi Arabia and Mediterranean countries. (who.int)
The sickle-cell gene has become common in Africa because the sickle-cell trait confers some resistance to falciparum malaria during a critical period of early childhood, favouring survival of the host and subsequent transmission of the abnormal haemoglobin gene. (who.int)

In recent years, anthropologists around the world have discovered new human ancestors , figured out what happened to the Neanderthals, and pushed back the age of the earliest member of our species. (businessinsider.com)

The Gastrotheca guentheri frog species evolved lower-jaw teeth after they'd been lost in the frog lineage. (nationalgeographic.com)
Of the more than 6,000 species of frogs, only one, a South American marsupial tree frog called Gastrotheca guentheri, has teeth on both its upper and lower jaws. (nationalgeographic.com)
In his study, Wiens used statistical methods to trace the evolution of teeth on the family tree of 170 amphibian species to frogs' common ancestor. (nationalgeographic.com)
An alternate theory is that lower-jaw teeth were lost in hundreds of other frog species but not G. guentheri. (nationalgeographic.com)
With that in mind, natural selection-the process by which favorable traits become more common over time within a species-is "not enough to explain" why the marsupial tree frog regained its lower teeth. (nationalgeographic.com)
The lower jaw, nicknamed El Graeco by the scientists, has additional dental root features, suggesting that the species Graecopithecus freybergi might belong to the pre-human lineage. (utoronto.ca)

Researchers at University of California, San Diego, suggest that the ancestors of modern humans may have caught herpes virus from chimpanzees before going their separate ways on the evolution path. (medindia.net)
According to the study, the ancestors of modern humans were infected by the Herpes Simplex Virus-1 from chimpanzees more than 6 million years ago, before the evolutionary split, while Herpes Simplex Virus-2, which causes genital warts, jumped from chimpanzees to Homo erectus 1.6 million years ago, long before the rise of early modern humans. (medindia.net)

Sickle cell disease is the most common inherited blood disorder in the United States, affecting an estimated 100,000 Americans. (medlineplus.gov)

Lower-jaw teeth in frogs re-evolved after an absence of 200 million years, a new study says. (nationalgeographic.com)
A new analysis of the frog family tree reveals that the common ancestor of frogs, which long had lower-jaw teeth, lost them more than 230 million years ago before eventually going extinct. (nationalgeographic.com)
In other words, the frog "didn't have to make teeth on the lower jaw from scratch, because they're already making them on the upper jaw. (nationalgeographic.com)
These animals have fanglike teeth on the upper jaw and have in some cases evolved toothlike spikes on the lower jaw. (nationalgeographic.com)
But, unlike G. guentheri, these lower-jaw spikes are not true teeth. (nationalgeographic.com)
