Answer:
I would personally recommend taking AP courses for any medical degree. Many colleges or universities consider AP and IB classes to be equal, and unless you are planning to go to college/university out of the US, Advanced Placement classes will be more accepted. Another reason why I would advise against IB classes is that it is not worth it to only take specific classes and is more beneficial to take the full diploma course. Some places will allow you to take individual classes instead of the full program like you would in AP, but it is not a guarantee. AP classes allow you to specialize more and avoid any classes you feel particularly weak in.
Answer: Evolutionary Psychology Explains Behavioral Skills
The ability to communicate complex thoughts was beneficial for human survival, and, as a result, language acquisition abilities evolved and advanced through the process of natural selection
~Hello There!~
So, I read up on this just to answer this question. In basic terms, it revolves around natural selection. Natural selection is simply when the organisms that are 'better adapted' live on to pass on their genes. The animals that aren't the 'better adapted' have to find ways to survive. This is what leads to the development of these relationships. For example, small insects may climb onto animals to get food. The organisms support each other. Does that help?
Hope This Helps You!
Good Luck :)
Have A Great Day ^_^
