Question

Accepted Answer

### Question 14
# Brief Explanations:
Speciation is defined as the process by which new biological species arise. Extinction is the end of a species, fossilization is the process of preserving organisms as fossils, and migration is movement of organisms. So speciation is formation of new species.
# Answer:
D. Formation of new species

### Question 15
# Brief Explanations:
Fossils are the preserved remains or traces of organisms from the past. They do not show future life, artificial selection is human - driven selection, and fossils are not direct evidence of climate change (though they can sometimes be related indirectly). So fossils provide evidence of past life.
# Answer:
B. Past life

### Question 16
# Brief Explanations:
Homologous structures are structures in different species that are similar because of common ancestry. They do not suggest different ancestry (they suggest the opposite), random chance is not related, and they may have different functions (e.g., human arm and bat wing). So homologous structures suggest shared ancestry.
# Answer:
C. Shared ancestry

### Question 17
# Brief Explanations:
Embryology is the study of the early development of organisms, from fertilization to the fetal stage. It does not study fossils, DNA (that's more genetics), or adult animals (that's more anatomy or zoology of adults). So embryology studies early development.
# Answer:
D. Early development

### Question 18
# Brief Explanations:
Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. Genetics is about genes, anatomy is about the structure of organisms, and fossil age is studied in paleontology (dating fossils). So biogeography studies species distribution.
# Answer:
B. Species distribution

### Question 19
# Brief Explanations:
Darwin delayed publishing his theory of evolution by natural selection because he was afraid of the criticism he would receive from the scientific community and the public, especially due to the religious implications of his theory. Lack of evidence was not the case (he had extensive evidence), illness was not the main reason for delay, and travel was part of his research, not a delay factor for publication. So fear of criticism delayed his publication.
# Answer:
C. Fear of criticism

### Question 20
# Brief Explanations:
Alfred Russel Wallace developed a theory of evolution by natural selection that was similar to Darwin's. Lamarck had a different theory of evolution (inheritance of acquired characteristics), Henslow was Darwin's mentor, and Malthus' work on population influenced Darwin's thinking but he didn't develop a similar theory to Darwin. So Wallace developed a similar theory to Darwin.
# Answer:
B. Wallace

### Question 21
# Brief Explanations:
Charles Darwin's "On the Origin of Species" was published in 1859. 1831 was when Darwin set sail on the Beagle, 1836 was when the Beagle returned, and 1882 was the year of Darwin's death. So it was published in 1859.
# Answer:
C. 1859

### Question 22 (assuming the numbering is a typo and it's question 22)
# Brief Explanations:
Some people opposed Darwin's theory because it contradicted the prevailing religious views of the time (the idea of special creation) and also because, at the time, it was thought to lack sufficient evidence (though in hindsight we know there is a lot of evidence). The theory was not too complex for opposition on that basis, and the lack of evidence was a perception at the time. So one reason for opposition was that it lacked evidence (perceived at the time).
# Answer:
B. It lacked evidence
