Evolution Lab
As time passes, people change over time. Life right now isn’t the way it was 21 centuries ago. And it’s not just us humans that’s changed; It’s all living things. This change over time or ‘development’ is called evolution. Evolution is the change of (heritable) traits in different organisms over time. If you’re thinking apes becoming humans you’re already wrong. There’s even evidence of evolution like fossils, DNA samples, similarities in bone structure, and even vestigial organs. The purpose of this lab is to see how evolution works and whether it is a reliable theory.
Hypothesis: If there are 11 skulls that all have different structures 4 of them will be bipedal.
Independent variable: Is all the measurements of each skull

Those skulls had the most similar traits to humans and were bipedal (walked on two feet). The rest of the skulls were quadrupedal. I predict that because of the ardipithecus and australopithecus environment and the way they lived is what made them look a lot like humans. Even though all of them are now extinct we were able to conclude how they looked and the way they lived because of their skulls.
Conclusion: While conducting this experiment I have come to the conclusion that my hypothesis was rejected. My hypothesis stated that 4 of the skulls would be bipedal. It turned out that five of them were bipedal. All of the the skulls in the ‘homo’ section were bipedal. The reason why many people think humans evolved from apes is because our structure is similar but as you learned that is not the case. As time passed humans have evolved in many ways. Based solely on the skulls from the ‘homo’ section, as you went ahead to the next one the heads became a little bit smaller. Also the zygomatic (cheek) bone shrunk. We humans are species that have evolved in many different ways over a long period of
