Scientists believe that all eukaryotes share a common ancestry because the nucleotides that make up all eukaryotic DNA are?
Scientists believe that all eukaryotes share a common ancestry because the nucleotides that compose their DNA are fundamentally similar in structure and sequence. This genetic uniformity suggests a shared evolutionary origin. Additionally, the presence of similar cellular structures and processes, such as membrane-bound organelles and complex regulatory mechanisms, further supports the idea of a common ancestor among eukaryotes. Overall, these genetic and structural similarities provide strong evidence for their shared lineage.

WHAT PERCENTAGE OF THE NUCLEOTIDES OF A CHICKEN ARE DIFFERENT FROM THOSE OF A MOUSE?
Approximately 20% of the nucleotides in the genomes of chickens and mice are different. This reflects the evolutionary divergence between birds and mammals, resulting in significant genetic variation. However, both species share a substantial amount of genetic similarity due to their common ancestry.
What evidence exists to support the idea that archaea are more closely related to eukaryotes rather than to bacteria?
The presence of certain genetic and molecular features, such as introns, histones, and similarities in the RNA polymerase structure, suggest a closer evolutionary relationship between archaea and eukaryotes. Additionally, comparative genomics studies have shown that archaea share more genes and metabolic pathways with eukaryotes than with bacteria. This evidence supports the hypothesis that archaea and eukaryotes share a common ancestry.
Do humans belong to the archaea?
No, humans do not belong to the Archaea domain. Humans are classified as eukaryotes within the domain Eukarya, which includes all organisms with complex cells containing a nucleus. Archaea, on the other hand, are a separate domain of prokaryotic microorganisms that are distinct from bacteria and eukaryotes. While humans and archaea share some common ancestry at a very basic level, they are fundamentally different in terms of cellular structure and biological classification.
What happened in our recent ancestry that did NOT happen in the chimps recent ancestry?
An event that happened in our recent ancestry that did not happen in the recent ancestry of chimps was the Industrial Revolution.
What do scientists feel that the genetic code helps to show proof of?
Scientists believe that the genetic code provides evidence of common ancestry among all living organisms and the process of evolution. The universal presence of genetic material in all living beings suggests a shared evolutionary history and the transmission of genetic information from one generation to the next.
Evolution states that land existed before the oceans is it true scientifically?
Evolution states that species share common ancestry, going back to just one or a select few original forms. Current models suggest prokaryotes, eukaryotes and archaea may have distinct origins, but all eukaryotes, for example, would have evolved from some original eukaryotic organism. This says nothing about land and water. Geology indicates ocean covered much of earth's surface from very early on.
How do scientists use pedigrees?
The pedigrees of an organism reflect to its ancestry. The scientists use pedigree record for breeding purposes in plants as well as in animals to get improvement in their races.
How do you use Common Ancestry in a sentence?
Common ancestry refers to the shared biological heritage between two or more species, indicating that they all descend from a common ancestor. For example, scientists study common ancestry to understand the evolutionary relationships between different species and trace their evolutionary history.

What are some artifacts or evidence that you can look at to study common ancestry?
Scientists can study common ancestry through artifacts like fossils, genetic similarities, and anatomical structures in species. Fossils provide evidence of extinct species, genetic similarities show shared ancestry between organisms, and anatomical structures reveal common traits inherited from a common ancestor.
What is the ancestry of Jared Leto?
He has Cajun ancestry
What happened in our recent ancestry that did NOT happen in the chimps recent ancestry?
An event that happened in our recent ancestry that did not happen in the recent ancestry of chimps was the Industrial Revolution.

What can homologies reveal about evolution?
Homologies, similarities in structure or genetic sequence among different species, can reveal common ancestry and evolutionary relationships. Studying homologies can help us trace the evolutionary history of organisms and understand how they have diversified over time. By comparing homologous traits, scientists can infer the shared ancestry and evolutionary pathways of organisms.
What are two ways scientists can investigate telatedness between organisms?
Scientists can investigate relatedness between organisms through DNA sequencing, which can reveal genetic similarities and differences. They can also use phylogenetic analysis to study evolutionary relationships based on shared ancestry and common characteristics.
Who studys ancestry?
Genealogists and historians study ancestry
