evolve: what is macroevolution vs. microevolution?

When studying the life sciences, there are a lot of in-depth concepts to take in. Depending on the the type of science you are studying, biology vs. evolution, for example, you may even have to learn a handful of mathematical formulas to fully appreciate the material. Here, we are just having a light-hearted overview of the life sciences, so a light serving of sativa will do just fine.

In my experience, sativa helps me to not get lost in wordy texts (reading that is not broken up by graphics/tables or formulas) and keep my mind sharp and able to take in all relevant information. Grinding about 60mg (less than 1/4 of a 1g bud) of sativa and smoking just a small pinch of that for over a 3-5hr period is perfect for maintaining a healthy attention span for learning.

Microevolution vs. Macroevolution

Oh, evolution. One of my favorite topics EVER. It’s a real shame that some people still don’t “believe” in the evolution of animals. Truth is, you don’t have an option on whether evolution is real or not. Where the choice lies is in your opportunity to learn about it or not. That said, I’m glad you’re here!

So what is macroevolution? Well, there are two main types of evolution, micro and macro. To put it succinctly, microevolution is focused on the… well, micro level. Genetics, and that stuff.

Microevolution is concerned with several things, all of which are related to these two factors:

  • The way that alleles (locations of specific genetic traits in your DNA) interact with one another
  • The rise of dominant traits over submissive characteristics

It’s the “Behind the Scenes” of the star of the show (in my opinion): macroevolution!

Now, while I do enjoy genetics talk to an extent, I’m more of a big picture gal. That’s where macroevolution comes in.

One widely accepted macroevolution definition says that it is the process of gradual genetic change manifested in organisms’ outward appearances, or their phenotypes.

(GENotypes = genes; PHENotypes = physical appearance, and other ways that the genes are expressed).

In fact, that may be why it persists as my favorite over microevolution – because we can see it happening, it is so much more dramatic!

What is Speciation?

One of the best examples of macroevolution is a phenomenon called “speciation.” Speciation can happen in a number of ways, one of them being the division of one species into two! How does this happen?

This division can happen in several ways: it starts with geographic separation (valley, highway, etc.). If the animals are separated for an extended period of time, they may begin to develop different behavioral patterns, so much so that they forget what each other acts like.

These behavioral differences can become pretty extreme over time and the animals may start to develop different mating seasons, different vocalizations, and eventually become so distinct that they no longer mate with each other.

So here’s the tricky part: if they can reproduce successfully if they ever meet and mate again, then they can either be considered to be the same species or the same subspecies.

But, if they cannot produce viable offspring (meaning their offspring either don’t survive or cannot successfully produce offspring themselves), then they are considered to be two separate species! See? It’s that simple!

(This speciation definition only holds up according to the biological species concept. Otherwise, species divergence – the evolutionary separation of a species from its ancestral organism – is not this simple.)


As the world continues to change, wildlife is constantly evolving in attempts to adapt to the circumstances humans repeatedly force them into.

They change their behavior, learn human behaviors to avoid or exploit them, and so much more. Stick around to learn more about all the different ways wildlife and the environment evolves around us every day.
