It's a complicated answer. Every living organism on the planet can trace its roots all the way back to one organism -primitive precambrian bacteria. A colony of bacteria was probably separated into two colonies which were then isolated. Both groups were probably faced with different environmental challenges. Only the bacteria with the adaptations that kept them from dying survived long enough to split themselves and reproduce. That's how evolution works. Every time a group of organisms is isolated and each one is relocated in has different environmental factors, only the ones with the right stuff will make it. Eventually the separate groups will evolve into completely different species as their helpful adaptations are amplified through the generations, but the original group from which they both came is their common ancestor. I'm not sure if I explained that clearly enough, but that is how different organisms share a common ancestor.
What else can I help you with?
What does the presence of Similar genes in very dissimilar organisms imply?
The presence of similar genes in very dissimilar organisms implies a common ancestor. This suggests that these organisms share a common evolutionary history and have inherited these genes from a common ancestor. The concept is known as homology.
A group of organisms have the same traits?
If a group of organisms have the same traits, it could indicate that they belong to the same species or share a common ancestor. These shared traits could be the result of genetic inheritance or environmental factors influencing their development.
How can you use classification to tell how closely organisms are related?
Scientists mainly compare similarities and differences in what the organisms look like. With the less obvious relations, they analyze their DNA. The goal is to find a common ancestor between the two organisms. The more recently that ancestor existed, the more closely related the organisms are.
How do different organisms have the same subset of genes?
Different organisms can have the same subset of genes through processes like gene duplication, vertical gene transfer, and lateral gene transfer. Gene duplication can lead to multiple copies of the same gene in different organisms. Vertical gene transfer involves the inheritance of genes from a common ancestor. Lateral gene transfer allows organisms to acquire genes from other species, leading to the sharing of genetic material among organisms.
What happens when two organisms attempt to occupy the same niche-?
Massive competition occurs when 2 organisms have the sane niche. The organisms are 2 species.
What does it mean for species to have an evolutionary relationship?
If two organisms share an evolutionary relationship, that means that they have a common ancestor on the evolutionary tree. The more recently the shared common ancestor lived, the more closely related the two present organisms are, evolutionarily.
What does the presence of Similar genes in very dissimilar organisms imply?
The presence of similar genes in very dissimilar organisms implies a common ancestor. This suggests that these organisms share a common evolutionary history and have inherited these genes from a common ancestor. The concept is known as homology.
Did all the people in the world came from a same ancestor?
yes the did how do you think other organisms start to exist
Which organisms have possible common ancestor?
All of them
What are Descendant organisms?
Descendant organisms are organisms that share many in common because they share a common ancestor.
A group of organisms have the same traits?
If a group of organisms have the same traits, it could indicate that they belong to the same species or share a common ancestor. These shared traits could be the result of genetic inheritance or environmental factors influencing their development.
What does the FOXP2 gene in mammals tell us about evolutionary relationships?
That those organisms that posses this gene have the same common ancestor that they all branched from and developed from.
What is the definition of ancestral trait?
An ancestral trait is a trait that is shared by a group of organisms and their common ancestor. It is a characteristic that has been inherited from a common ancestor and has been passed down through generations without change.
Explain the evolutionary significance of a nearly universal genetic code?
It is considered universal because all organisms use the same codon for the same amino acid.
What is our evidence of Luca, the common ancestor that we can link all living organisms to?
Scientists have identified Luca as the Last Universal Common Ancestor, or the common ancestor of all living organisms. Evidence for Luca comes from the study of genetic material and the similarities found in the genetic code of different species.
What is an evolutionary?
If two organisms share an evolutionary relationship, that means that they have a common ancestor on the evolutionary tree. The more recently the shared common ancestor lived, the more closely related the two present organisms are, evolutionarily.
