no you can't. It's people who are unfamiliar with science that say that. Just because there are a lot of guesses doesn't mean they haven't been very thoroughly researched. Evolution comes down to 2 things. Which mutations end up making an animal either a) reproduce more or b) live long enough to reproduce several times. And actually, the size of our brain cavity is what allows us to have such a large brain. In fact, the most sizable portion of our brain is the cortex, which is notably small or absent in most other creatures. It is this cortex that is involved in highly skilled action, abstract thought, understanding of cause and effect, long term memory, planning, and complex motor skills like multi-tasking. And you are correct that having a bigger brain than someone else doesn't make someone smarter, but having a bigger brain than another animal is a near infinite difference. Seeing over tall grass is a very valid possibility. Almost every animal has the ability to stand on hind legs for short durations when scouting out areas. |
This is no researching we walk upright because we can see over grass as if every example there are counter examples. Because of so many counter examples found in nature evolution has to cover everything which in turn explain nothing.
Continuely standing straight up also has it's disadvantage just like a sub continuely using active sonar. Thus other animals can easily see you before you see them.
