In the context of family relationships, what is the significance of a 'common ancestor'?
In the context of family relationships, what is the significance of a 'common ancestor'?
- It signifies the oldest living relative in a family.
- It refers to the individual who started tracing the family tree.
- It represents the point where two different family trees merge, indicating a shared genetic link. (correct)
- It is a term used to describe relatives who live in the same household.
How does the concept of 'relatedness' among species relate to the idea of a family tree?
How does the concept of 'relatedness' among species relate to the idea of a family tree?
- Species relatedness is determined by comparing physical characteristics, similar to how family members resemble each other.
- The concept of relatedness is purely based on scientific classification and has no connection to the idea of a family tree.
- Species are considered related if they inhabit the same geographical location.
- The history of each species can be traced through a family tree of relationships to other species through common ancestors. (correct)
What is 'speciation'?
What is 'speciation'?
- The process by which different species merge into a single species.
- The study of the geographical distribution of species.
- The identification and classification of different species.
- The process where one species evolves and splits into two or more new species. (correct)
In terms of evolutionary relationships, what does it mean for two species to be 'distantly related'?

Study Notes
Related Organisms
-
"Close" relatives include siblings and parents
-
"Distant" relatives include aunts, uncles, and cousins
-
Tracking goes as far as great-grandparents, and second or third cousins
-
The closer a relative, the more recently they attach to your family tree
-
The point where family trees join is a common ancestor
-
The common ancestor is the reason for relatedness
-
Siblings are more closely related than cousins
-
Siblings share parents, while cousins share grandparents
-
Siblings have a more recent common ancestor than cousins
-
Similar concepts can be applied to the relatedness of all living things
-
Speciation is when one species gives rise to several new species
-
The history of each species tracks through a family tree of relationships to other species
-
Closely related species share a recent common ancestor
-
Distantly related species require going further back in the history of life to find a common ancestor
Experiment Note
- Focus is on different species of animals and declaring closely related pairs
- This is based on which groups they belong to
- The closer the group, the more recent the common ancestor between them
