What are Descendant organisms?
Descendant organisms are organisms that share many in common because they share a common ancestor.
Do dragons and vampires share a common ancestor?
There has been no evidence of such an ancestor.
Why the homologous structures are evidence of evolutionary relationship?
They show similarities between organisms structure. if the similarities are large then it shows that those organisms share a common ancestor.
Does the theory that organisms share a common ancestor is known as common descent?
Yes, that is true.
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 organisms share the most recent common ancestor?
Organisms that share the most recent common ancestor are those that are closely related in evolutionary terms, such as humans and chimpanzees. They both belong to the family Hominidae and diverged from a common ancestor about 6 to 7 million years ago. Other examples include all mammals, which share a common ancestor that lived around 200 million years ago. The concept of a common ancestor highlights the interconnectedness of life through evolutionary processes.
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.
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.
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 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.
Do seals and humans share a common ancestor?
yes they do in facts share a common ancestor.
