If you were a scientist examining the DNA sequence of two unknown organisms that you hypothesize share a common ancestor what evidence would you except to find?
I would expect to find similarities in their DNA sequences, such as similar genes or genetic markers, that suggest a common evolutionary history. These similarities may include shared gene sequences, regulatory elements, or other genetic features that indicate a shared ancestry. Additionally, I would look for differences in the DNA sequences that have accumulated over time, reflecting the divergent evolution of the two organisms.
What else can I help you with?
What are 2 ways that organisms can be compared to provide evidence of evolution from a commo ancestor?
Organisms can be compared through anatomical similarities, where shared structures suggest a common ancestor. They can also be compared through molecular evidence, such as DNA sequences, to reveal genetic relationships and common ancestry.
Why do scientist believe that all life on earth evolved from a singe celled ancestor?
Scientists believe that all life on Earth evolved from a single-celled ancestor because of the similarities found in the genetic code and cellular structure of all living organisms. This suggests a common origin and shared ancestry. Additionally, the gradual changes observed in the fossil record and the patterns of biodiversity support the idea of evolution from a common ancestor.
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.
How would you know if organisms shared a common ancestor?
Scientists can determine if organisms share a common ancestor by analyzing their genetic and morphological similarities. The more similarities that exist, the more likely it is that they share a common ancestor. Additionally, the study of evolutionary relationships through techniques like phylogenetic analysis helps to trace back common ancestry among organisms.
If you compare organisms with similar characteristics what indicates recent their common ancestor probably is?
The more similar the genes and traits of the organisms are, the more recent their common ancestor is likely to be. The presence of shared genetic sequences or homologous structures can also indicate a more recent common ancestor. Additionally, proximity in the evolutionary tree of life and geographic proximity can also suggest a recent common ancestor.

In the early 1800s Darwin studied 13 kings of finches what did Darwin hypothesize about these birds?
The finches were different species that shared a common ancestor
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.
How can a scientist tell of two species share a common ancestor identify three ways?
A scientist can determine if two species share a common ancestor by examining genetic similarities through DNA sequencing, which can reveal shared genetic markers. Additionally, they can analyze morphological traits to identify structural similarities that may indicate a common evolutionary origin. Lastly, studying the fossil record can provide insights into the evolutionary history and transitional forms between species.
Why do scientist think green algae and plants have a common ancestor?
They share chlorophyll.
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.
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.
What is cladistics?
A system that groups organisms by ancestry

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.
