What are Descendant organisms?
Descendant organisms are organisms that share many in common because they share a common ancestor.
Similar features in organisms that do not share a recent common ancestor are the result of what?
Similar features in organisms that do not share ancestry means both organisms adapted to their environment. They developed the features to survive.
What does the diagram imply about the peafowl and the chicken?
They share a recent common ancestor.
What does it mean if two organisms share many levels of classification?
If two organisms share many levels of classification, it indicates that they have a close evolutionary relationship and likely share a more recent common ancestor. Their similarities in classification suggest that they have many characteristics and genetic traits in common.
Does the theory that organisms share a common ancestor is known as common descent?
Yes, that is true.
Which group of organisms would have the most recent common ancestor the members of a clade corresponding to a genus or the members of a clade corresponding to an order?
The group of organisms within a genus would have the most recent common ancestor compared to a group within an order. This is because a genus represents a subset of species that are more closely related and share a more recent common ancestor than the broader group represented by an order.
How do cladograms work?
You start with the bottom up ones , trace until you find the node where the line branches out , this means you have found two organisms that share a recent common ancestor
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.
How are the organisms on a branching tree diagram grouped?
Branching tree diagrams (or cladograms) attempt to show the ancestral relationships between species. The groupings indicate relatedness - closely grouped organisms will be more closely related (sharing a more recent common ancestor) than organisms which descend from earlier divisions, which will be further away on the cladogram.
Do seals and humans share a common ancestor?
yes they do in facts share 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.
