Evolution ------Darwin
I believe we evolve from apes, because some scientists have already proved that apes is the most similar species with human. There are too many the same characteristics. On the other hand, I have heard a story. Long long time ago, spes all lived on the tree, because food was not enough for them, therefore some of them tried to descover the land. This group of spes began to use 2 legs to walk, and learnt to make a tool to kill other animals for food, then they developed and developed , until now they evolve to human. Other spes who did not follow them become champs,monkey,etc. So I really believe this is ture.

This is an interesting story Alden. Actually it makes me think about Darwin's theory anyway : since there was not enough food in the trees, future humans discovered life on the land and they adapted to their new environment using their legs and hands (like the iguanas. See u tomorow!! :)
ReplyDeleteIn my opinion, I agree with this idea that more species change over times, in order to adapt to their environment. Also, I believe my ancestor could evolve from apes. According to all of the studies during several weeks, these videos, reading, and lecture let me understand clearly how and why several species change over times for adapting to their environment changing. In order to keep more health and stronger offspring, they need to adapt to their living environment. Then, these survives can keep their species’ gene for longer time. Maybe several parts of species require changing for adapting to environment in short-period time. In Darwin’s theory, he called this process of changing is natural selection. Moreover, human beings still is changing over times in modern society, in order to adapt to our environment and future. As a result, I believe human beings could evolve from apes also. Although the size of brain is the biggest gap between apes and us, we have several similar bodies’ parts such as hands and mouth. Depended on several fossils, apes had evolved in order to adapt their environment changing. For example, apes cannot stand up to see as backing in 400 millions years, but they tried to stand up and walk later because of seeing more far places for protection. Then, apes’ offspring had evolved to adapt their environment with their gene which changes their structure of bones to stand till today. At present, scientists have found with new technology that some apes’ DNA is closely similar to human beings’. There is a evidence for proving human beings evolved from ape
