Which of the following statements best represents Lamarck's view on evolution? —
Organisms adapt to their environment by acquiring traits through use and disuse, which are then inherited.

Providing a mathematical framework for understanding changes in allele frequencies
15.

According to Darwin's theory, evolution occurs at the level of: —

20.
According to Lamarck's theory, how did giraffes acquire their long necks? —

What is the primary mechanism of evolution proposed by Charles Darwin? —
Natural selection
22.

Charles Darwin
23.
The 'Origin of Species' was a seminal work published by: —
Charles Darwin
24.
Lamarck's theory of evolution was influential in its time but is largely discredited today due to: —
The absence of a mechanism for inheritance of acquired traits
25.
The modern evolutionary synthesis provided a robust explanation for evolution by combining Darwin's theory of natural selection with: —
Mendelian genetics and the concept of mutation.
26.
The 'synthesis' in the modern evolutionary synthesis refers to the integration of: —
Genetics and Darwin's theory of natural selection
27.
Darwin's theory of natural selection predicts that over time, populations will become: —
More suited to their environment
28.
The 'synthesis' in evolutionary synthesis is crucial because it reconciled Darwin's ideas with: —
Mendelian genetics, which explained the mechanism of inheritance
29.
The modern evolutionary synthesis reconciled Darwinism with genetics by demonstrating that: —
Natural selection acts on discrete units of inheritance (genes).
30.
Lamarck's theory of evolution is primarily based on which of the following principles? —
Inheritance of acquired characteristics and use and disuse of organs
31.
The modern evolutionary synthesis is a robust framework that explains evolution through the interplay of: —
Natural selection, genetic drift, mutation, and gene flow
32.
A key difference between Lamarck's and Darwin's theories lies in the mechanism of change. Lamarck emphasized ________, while Darwin emphasized ________. —
inheritance of acquired traits; natural selection
33.
Which statement best reflects the core idea of Darwin's theory of natural selection? —
Individuals with traits better suited to their environment are more likely to survive and reproduce, passing those traits on.
34.
The 'use and disuse' principle, proposed by Lamarck, suggests that: —
Organs that are used more become stronger and larger, while those not used atrophy.
35.
The Neo-Darwinian synthesis, or the modern evolutionary synthesis, primarily addresses the lack of a clear mechanism for inheritance in Darwin's original work by incorporating findings from: —
Genetics
36.
Darwin's theory of evolution is supported by evidence from which of the following fields? —
Paleontology, comparative anatomy, embryology, and biogeography
37.
The concept of 'fitness' in Darwinian evolution refers to: —
Ability to survive and reproduce in a particular environment
38.
Darwin's theory of natural selection explains the 'fit' between organisms and their environment as a result of: —
Differential reproductive success
39.
Alfred Russel Wallace's contribution to evolutionary theory was significant because he: —
Independently developed a theory of evolution by natural selection.
40.
The modern synthesis, developed in the mid-20th century, is considered a cornerstone of evolutionary biology because it: —
Unified genetics, paleontology, and evolutionary theory.

Organisms have an inherent drive towards complexity.
42.
The evolutionary thought of Jean-Baptiste Lamarck is characterized by: —
