What is molecular homology?
Similarities among organisms at the molecular level due to a shared ancestry. Learn more at 23andme.com.
Is sexual reproduction among plants common?
yes.
What are the four pieces of evidence that scientists point to as proof of natural selection?
Among myriad others; fossil evidence, artificial selection, biogeographic distribution of organisms and molecular genetics.
What is the purpose of a TSI test?
To differentiate among the different groups or genera of the Enterobacteriaceae, which are all gram-negative bacilli.
What is the most common brain disease affecting young adults?
the most common disease among young Americans is "narcissism"
What data is used in systematics that stresses both common ancestry and the amount of change observed among groups?
The data that is used in systematics that stresses both the common ancestry and the amount of change that is observed among groups is cladistic. Cladistic is the classification in which items are grouped together.
Is Chick a nickname for Charles?
It is. Chick is a nickname most common among people of Irish ancestry, although it is found in other groups as well
What provide common ancestry among organisms?
Simularities in DNA sequence
What evidence indicates relationship among vertebrate groups?
The evidence for there relationship is that they both have back bones and skulls
What ethnic group is most likely to get polydactyly?
It is most common among those of African ancestry.
Was there ever evidence of slavery in Africa among indigenous people?
Yes there was between various tribal groups.
Did australopithecus afarensis live in groups?
It is likely that Australopithecus afarensis lived in social groups, as evidenced by evidence of group coordination and possible division of labor among individuals. Fossil evidence also suggests that they lived and traveled together in groups for protection and cooperation.
Do Armenians have Persian ancestry?
Armenians and Persians, together with the other Iranian people, are of the Aryan race. I strongly believe that the amount of Armenians with Persian ancestry is very high because of the past (origins). Note: Armenians who have surnames that are also common among Persians, have Persian ancestry.
What area of taxonomy classifies organisms based on common ancestry?
Phylogenetics classifies organisms based on common ancestry by analyzing their evolutionary relationships using genetic data. This field of study helps to understand the evolutionary history and relatedness among different species.
What does evidence suggest about the human origins?
Evidence suggests that early humans evolved in Africa around 200,000 years ago. Fossil discoveries and DNA analysis support the theory that modern humans, Homo sapiens, originated in Africa and eventually migrated to other parts of the world. Genetic studies show a common ancestry among all modern humans.
What evidence do these similar structures provide in support of evolution?
Comparative DNA samples from chimpanzees and humans show very well the concept of evolutionary common ancestry. Aside from that, the differences in DNA among organisms, especially at certain loci, show how long two, or more, organisms shared common ancestry.
How does the incidence of gasteroenterologic diseases differ among ethnic groups?
The incidence of gasteroenterologic diseases differs among ethnic groups. For instance, while gastroesophageal reflux disease (GERD) is common in Caucasians, its incidence is lower among African Americans.
