Question

tran made the timeline below to show the order in which great scientific theories were developed.
theory of gravity → cell theory → ? → theory of continental drift
which theory belongs in place of the question mark in trans timeline?
○ aristotles atomic theory
○ newtons laws of motion
○ copernicuss heliocentric theory
○ darwins theory of natural selection

Explanation:

Step1: Determine time periods

• Theory of gravity (Newton, 1687).
• Cell theory (1838 - 1839).
• Continental drift (Alfred Wegener, 1912).

Step2: Analyze each option

• Aristotle's atomic theory (4th century BC - too early).
• Newton's laws of motion (1687 - same time as gravity theory).
• Copernicus's heliocentric theory (1543 - too early).
• Darwin's theory of natural selection (1859 - fits between cell theory and continental drift).

Answer:

Darwin's theory of natural selection
