>>12530935>>12530896The easiest/most accessible way to learn evolutionary biology is to start with human evolution, since the textbooks in that field are the most common and the most entry level. They are included in many first-year courses in general biology, archaeology, psychology for instance.
Most books an evolutionary biology in general in all life will tend to be a bit more advanced and will often focus on second or even third-year courses.
So, a good starting point is a book like this:
https://www.amazon.com/Humans-Evolved-Eighth-Robert-Boyd/dp/0393603466 It's simultaneously criticized and lauded for being very "entry-level", and it picks up speed and goes more and more in-depth as it goes along. You can just read the first chapters, which start with general evolutionary theory to try to understand our ancestors from the past 100 million years and interpret the palaeontological remains, before it focuses specifically on humans.
When you read, try to really understand and THINK. You get better at THINKING, by practicing THINKING. Question everything you read and and encounter. Why, how, what, when, where, how does this work and why does this work how it works?
Practice mentally challenging activities regularly. Don't let the focus be to succeed or to accomplish your task/exercise, focus on being able to FOCUS on it. Focus on immersing yourself 100% in your activity, trying to fully absorb and understand every single facet of it. Just start and keep going. Even if it's a subject you might not be that interested in.
Start with a channel like this:

Look at your brain like a muscle and work it out like you would in the gym.
Oh and eat lots of artichoke, brussels sprouts and drink lots of kefir.
