QUESTION POSTED AT 26/03/2020 - 12:44 PM

Over millions of years, hominid species learned to use and create tools that became more complex over time. They eventually shaped stone into knives used for cutting, and they harnessed fire for light, heat, and cooking food. Which of the following best explains what effect this had on hominid evolution? Hominid front limbs became longer in proportion to the rest of their body. Hominid brain size decreased as life became easier with the advent of tools. Hominid tooth size decreased as they relied on cooked foods and tools for cutting. Hominid hands developed smaller thumbs as they developed finer tools.


The correct answer is hominid tooth size decreased as they relied on cooked foods and tools for cutting.


Ancient humans started using the tools which helped them in their survival.

This use of tools showed great influence on the evolution of human teeth as it leads to the decrease in the size of the teeth over time like the smaller size of wisdom or molar teeth in modern humans or Homo sapiens. This can be suggested by the fossil studies as the fossils of "a nutcracker" or Paranthropus boisei which lived around 2.3 mya had the largest molar teeth which decreased in modern humans.

The use of tools by humans took the functions done by the teeth like cutting the food into small pieces and also helped in cooking food which caused humans not to invest much energy on growing larger teeth but producing smaller teeth.

Thus, hominid tooth size decreased as they relied on cooked foods and tools for cutting is the correct answer.
