This week we looked at the documentary the Origin of us which tracked the process of human evolution and showed that it is largely related to our food. I thought this video was really interesting and presented an aspect of evolution I didn’t know much about. I learnt that humans are unique in our ability to see in red and green and that our ancestors could only see blues and yellow. By having this mutation to see a wider part of the electromagnetic field they could tell which fruit was ripe and thus had a better nutritional value. This was advantageous and thus humans evolved with the ability to see more colours.
I found the concepts of the effect of abiotic, biotic and technological factors interesting and want to explore more deeply the process of human evolution. I found this video and found it really helpful to further my understanding
