AI Thread Summary
The discussion centers on the evolution of humans and the role of DNA in physical changes over time. It raises questions about why humans have evolved from ape-like ancestors to modern beings with significant differences in appearance and functionality, such as bipedalism and larger brains. The conversation highlights that changes in DNA sequences, known as mutations, are responsible for the observable differences between species. The inquiry suggests a curiosity about the mechanisms of evolution and how genetic changes have led to the current state of human beings compared to their ancestors.

You need to make your question more clear, as I cannot understand what you are asking.
 
when before stone age,the human beings are like as a gorilla. i mean their appearance , using four legs to move ...etc... but now we have got changes . we have a big brain, use two legs to walk . so is it relating the changes of DNA,or others?
 
Changes (mutations) in the DNA sequences will give rise to the differences you observe between two species.

Thread 'Did they discover another descendant of homo erectus?'

The study provides critical new insights into the African Humid Period, a time between 14,500 and 5,000 years ago when the Sahara desert was a green savanna, rich in water bodies that facilitated human habitation and the spread of pastoralism. Later aridification turned this region into the world's largest desert. Due to the extreme aridity of the region today, DNA preservation is poor, making this pioneering ancient DNA study all the more significant. Genomic analyses reveal that the...
