Using your knowledge of hominid evolution, which of the following correctly associates the given brain capacities with the hominid species in the table in order from smallest to largest?

\begin{tabular}{|l|l|l|}
\hline \multicolumn{1}{|c|}{ Species } & \multicolumn{1}{|c|}{\begin{tabular}{c}
Time period \\
(millions of years ago)
\end{tabular}} & \multicolumn{1}{|c|}{ Tool use } \\
\hline A. afarensis & [tex]$3.6-2.8$[/tex] & Possible tool use \\
\hline A. africanus & [tex]$3.0-2.4$[/tex] & Possible tool use \\
\hline H. habilis & [tex]$2-1.5$[/tex] & Simple stone tools \\
\hline H. neanderthalensis & [tex]$0.13-0.035$[/tex] & Complex stone tools \\
\hline
\end{tabular}

A. H. neanderthalensis, H. habilis, A. africanus, A. afarensis

B. A. afarensis, A. africanus, H. habilis, H. neanderthalensis

C. A. afarensis, A. africanus, H. neanderthalensis, H. habilis

D. H. habilis, A. afarensis, A. africanus, H. neanderthalensis

To solve the problem of ordering hominid species by brain capacities from smallest to largest, we need to consider the different species and their associated brain capacities. We are provided with the following brain capacities:

1. A. afarensis: 430 cc
2. A. africanus: 450 cc
3. H. habilis: 600 cc
4. H. neanderthalensis: 1600 cc

We will now list these species in order of their brain capacities, starting with the smallest.

Step-by-Step Solution:

1. Identify the species with the smallest brain capacity:
- A. afarensis: 430 cc

2. Identify the species with the next smallest brain capacity:
- A. africanus: 450 cc

3. Identify the species that comes next in increasing brain capacity:
- H. habilis: 600 cc

4. Identify the species with the largest brain capacity:
- H. neanderthalensis: 1600 cc

By arranging the species in the correct order from smallest to largest brain capacities, we get:

- A. afarensis (430 cc)
- A. africanus (450 cc)
- H. habilis (600 cc)
- H. neanderthalensis (1600 cc)

Therefore, the correct sequence is:

A. afarensis, A. africanus, H. habilis, H. neanderthalensis

This sequence accurately orders the given hominid species by their brain capacities from the smallest to the largest.
