Tree Of Life

Question 1

lineage of organisms

Answer 1

Branches

Question 2

Points where branches split represent common ancestors

Answer 2

Nodes

Question 3

base of the tree shows the last universal common ancestor (LUCA) from which all life evolved

Answer 3

Root

Question 4

Branches split to form new lineages, showing evolutionary changes

Answer 4

Divergence

Question 5

Groups of organisms branching from a common node form, indicating they share a recent common ancestor

Answer 5

Clades

Question 6

-represents the evolutionary relationship among all living organisms, showing their common ancestry and the process of diversification over time

Answer 6

Scientific Perspective

Question 7

•reflects unity, balance, and harmony in nature, emphasizing the idea that all life is interconnected

Answer 7

Philosophical Meaning

Question 8

similar physical features in organisms that share a common ancestor, but the features serve completely different functions

Answer 8

Homologous structures

Question 9

-similar physical features in organisms that do not share a common ancestor. Relatedness is based entirely due to its same function

Answer 9

Analogous structures

Question 10

-two organisms that do not share a common ancestor evolve and develop similarities independently of one another
-these similarities form because the animals either live in comparable environments or they experience the same environmental pressures, resulting in the evolution of these features

Answer 10

Convergent

Question 11

-two organisms that do not share a common ancestor evolve and develop similarities independently of one another
-these similarities form because the animals either live in comparable environments or they experience the same environmental pressures, resulting in the evolution of these features

Answer 11

Convergent
