The statements that accurately describe the evolution of the hominid jaw are:
1. **Changes in diet most likely played a role in the change of jaw size.** - As hominids evolved and their diets changed (e.g., towards softer foods and cooked meals), this likely influenced the size and structure of the jaw.
2. **Modern humans have smaller jaws than their hominid ancestors.** - This is true; modern humans generally have smaller jaws compared to many of their hominid ancestors, which is thought to be related to changes in diet and cooking practices.
The other statements are not accurate:
- **Modern humans have larger jaws than their hominid ancestors.** - This is incorrect; modern humans have smaller jaws.
- **Modern humans need stronger jaws to compensate for a changed diet.** - This statement is misleading; modern human jaws are generally weaker and smaller due to dietary changes.
- **The development of language played a role in the changes in jaw size in hominids.** - While the capacity for language may be linked to changes in the vocal tract and facial structure, there is no direct evidence that it played a significant role in changes in jaw size.
