Accepted Answer

James Hutton

Question 2

According to Lamarck's hypothesis, how did organisms acquire traits during their lifetime?

Accepted Answer

By using or not using certain parts of their bodies

Question 3

Accepted Answer

$$N(t) = N_0$ 	imes e$$^{rt}$$

Question 4

Which of the following best describes artificial selection?

Accepted Answer

The breeding of organisms by humans to select for desired traits

Question 5

Darwin's theory of natural selection is based on which key principle?

Accepted Answer

Individuals with advantageous traits are more likely to survive and reproduce

Question 6

Which term describes the ability of an organism to survive and reproduce in its environment?

Accepted Answer

Fitness

Question 7

In the context of Darwin's finches, what is the most likely outcome if a drought reduces the availability of small seeds?

Accepted Answer

Finches with large beaks will be more likely to survive

Question 8

Which evidence supports the idea of common ancestry among species?

Accepted Answer

Homologous structures

Question 9

Which of the following is an example of a vestigial structure?

Accepted Answer

The tailbone in humans

Question 10

Biogeography provides evidence for evolution by showing:

Accepted Answer

How organisms are distributed across the planet

Question 11

Which equation would you use to calculate the change in allele frequency due to natural selection in a population?

Accepted Answer

$$\Delta p = p' - p$$

Question 12

Which of the following best explains why homologous structures are important evidence for evolution?

Accepted Answer

They indicate a common ancestor due to similar anatomy

Question 13

What is the significance of molecular homology in evolutionary biology?

Accepted Answer

It demonstrates that closely related species share similar DNA sequences

Question 14

Which scenario best illustrates the concept of 'survival of the fittest'?

Accepted Answer

A population of moths with camouflage survives better in polluted environments

Question 15

Which of the following is NOT a mechanism of evolutionary change discussed in Darwin's theory?

Accepted Answer

Inheritance of acquired traits

Question 16

How did fossil discoveries support Darwin's theory of evolution?

Accepted Answer

They revealed gradual changes in species over time

Question 17

Which of the following best describes analogous structures?

Accepted Answer

Structures with similar functions but different evolutionary origins

Question 18

Which real-world example demonstrates natural selection in action?

Accepted Answer

The increase in antibiotic-resistant bacteria due to overuse of antibiotics

Question 19

Which concept is illustrated by the branching tree model of Galapagos finches?

Accepted Answer

Common ancestry and adaptive radiation

Question 20

Which equation represents the Hardy-Weinberg equilibrium for allele frequencies in a population?

Accepted Answer
