Lucy's arms at first were very long; but as we became more prominent walking on land, the need for having long arms diminished. So, overtime the length of arms became shorter and more proportional. Which can be used to compare the evolution of how we are less dependent on our arms for transportation.

Length of body: Lucy had a smaller body and over time our bodies have gotten longer/ taller. We are no longer hunched over and as short as Lucy was.

As Lucy descended from the trees to the ground, her posture became more upright because as we adapted to walking more, having a upright back supported us more

lucy was a tree dweller which caused her to have a bigger upper body, and weaker lower body. Focusing on leg muscles, over time as humans didn't need to climb trees and instead had to walk and roam more, causing bigger and stronger leg muscles.

Lucy's arms were longer compared to her body than ours are compared to our own today. Lucy used her arms to climb and swing from trees, but we do not swing from trees so the need for longer arms became less needed.

The legs got longer due to the arms being lessed used for holding body weight and the legs had to be used to support the body weight while walking.

Her arms were longer in proportion to her body. Now compared to her, our arms are shorter in proportion to our body. I think this is because we have slowly gained les need for longer arms because we have moved from living in trees to now living on the ground so we don't need long tree climbing arms.

Bendable knees is present in both. In lucy's time knees did the same thing they do today. Lucy's knees and our knees have the same bone structure. Lucy use to jump from trees and her knees could handle the pressure of jumping down because of their knees. Human knees cannot handle that pressure. Our knees can not take this pressure mainly because we do not jump down from tre

One trait that was found on both lists were ankles. Lucy needed ankles in order to  climb trees and walk. Over time, ankles have become more flexible  and evolved. Ankles are necessary in order to move and walk around.

The long toes and the thumb-toe is used for both climbing and walking. This is an advancement during Lucy's time as a key for survival, making it easier to climb trees. Now, we don't have such long toes, nor do we have a thumb-toe, but apes do. Our feet are set at about 180 degrees and all toes are connected straight to the foot, making it easier to balance. I think this became adjusted over time because of walking and balancing.

A trait that was found under both colums for tree climbing and walking was "thumb toes". Thumb toes were very useful during lucy's time due to the fact that Lucy spent a lot of time in trees and climbing them. Though since we have evolved since Lucy's time no one has thumb toes anymore. No one has them because we no longer need to climb trees like Lucy we walk in todays society to get to different places so we no longer need them.

# data[].attributes.body
over time, toes have evolved since Lucy's time. The toes remain flexible and relatively the same however the toes have gotten shorter. We do not have a need to climb trees and use our toes as much for climbing and other uses like Lucy's time

# data[].attributes.body
Toes- Look the same but but have gotten smaller since Lucys time.

# data[].attributes.body
Wrists did not get more flexible over time because climbing and swinging from trees required more flexibility and now it is not used as much in nature. It changed because that trait was not as necessary as it was and people with that trait died out as fast as people without it. Balancing the traits out.

Studies have shown that Lucy had really strong arm bones that allow her to haul herself up branches, similar to how we were talking about her climbing up trees in our class discussion. During Lucy’s time, her limbs weren’t as strong, but her arms were surprisingly strong. This suggests she climbed and habited in trees and other high places. Now our arms aren’t as strong as hers as we don’t normally climb up trees or use our arms to an excessive amount. Her bones soon became bigger than ours due to all the activity she did with hers. They most likely were very flexible too.

Lucy's ankles lead to the conclusion that her feet were relatively flatter. This shared the same humanlike orientation as humans today, but they varied. If Lucy ever needed to climb a tree, it would be different to how humans would have climbed trees. Features of Lucy's feet and ankles show how human's feet and ankles displayed a long history of evolution little by little.

Something from Lucy's time that helped for walking and tree climbing were feet with a thumb on the side, like our hands. Since Lucy's time, thumbs on our feet have changed; we now have 5 toes on the top of each of our feet. Everyone has different toes, some may have extra toes or maybe even less . Although toes have changed a lot since Lucy's time, they still have a similar purpose. I believe that our toes help us balance, and help us to walk as well. I also think toes have become more flexible, which helps for walking, and different types of sports.

# data[].attributes.body
Our arms over the time have gotten smaller and shorter, we do not have it anymore because we do not have to climb trees anymore.

The long of arms of Lucy became shorter in proportion to the rest of the body. This is because as the hominids descended from the trees and onto the ground, there was a greater emphasis on walking on two legs instead of swinging from branch to branch.
