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 of evidence is used to show that organisms have a common ancestor?
Various types of evidence, such as fossil records, comparative anatomy, molecular biology (DNA sequencing), and biogeography, all support the theory of common ancestry among organisms. These sources provide clues that organisms share a common evolutionary history and have descended from a common ancestor. Comparing these pieces of evidence across different species helps scientists infer relationships and trace the evolutionary trajectory of life on Earth.
The fact that all organisms have DNA as their genetic material is evidence that?
all organisms share a common evolutionary ancestry. The universal presence of DNA suggests a common genetic code that has been inherited from a common ancestor. This supports the theory of evolution and the idea that all living things are connected through a shared genetic history.
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.
What type of animal was the common ancestor of mammals and birds?
The common ancestor of mammals and birds was a reptile.
Do dragons and vampires share a common ancestor?
There has been no evidence of such an ancestor.
What is our evidence of Luca, the common ancestor that we can link all living organisms to?

What is the evidence which shows that mollusks and annelids share a common ancestor?
Mollusks and segmented worms have a one-way digestive system, a separate mouth and anus, and their larvae are very similar. This is the best evidence that they have a common ancestor.
What evidence shows that the kingdom Protista have a common ancestor with plants?
Many protista contain chloroplasts.
Examples of biochemical evidence of evolution?
Physiological similarities suggest the species evolved from the same ancestor.
Describe three kinds of evidence suggesting that all primates might have shared a common ancestor?
Rape
What is an explanation of why bird wings and reptile forelegs are evidence of evolution?
Homologous structures indicate a common ancestor
What evidence can be used to show that organisms share a common ancestor?
The DNA genetic code provides the best evidence of the common ancestry of life. Science has shown that there are many similarities between DNA sequences.
How are vertebrate embryos evidence of evolution?
All vertebrate embryos look roughly the same, showing that they come from a common ancestor.

What is the common Ancestor of the horse and zebra and ass?
The common ancestor is the Hyracotherium
What further evidence would best substantiate that the two animals have a recent common ancestor?
The animals have very similar sequences in their DNA.
