 | Central Question:What do different evolutionary paths look like and how can we map them? Guiding Thought Question: Explain one of the things that will complicate determining a specie's Center of Origin. Center of Origins: Geographic location from which a certain species expanded from. Today's Learning Objective: Students will work through a mapping activity to learn about the diffusion of animals and how to trace their evolutionary paths from a common center. |

The different adaptations of a species that they developed over time.

If that species has relatives spread out throughout the world.

One of the things that would complicate determining a species center of origins is if the place’s location is no longer accessible like if it is now underwater or at the top of a mountain.

species migrations: the entire species moving from one place to another

A complication that can come up when determining a specie’s center of origin is that most animals migrate to different places and through time they evolve. Which makes them appear a little different than other members of their specie.

adaptations and evolution could make it hard to trace them back

One of the things that will complicate finding a species’ center of origin is topographical and geographical changes of the land. Changes of the land will move any fossils, or other items that are used as evidence to prove that the animal lived in an area, which makes finding the origin very difficult.

One thing that will complicate determining a species center of origin is, not being certain if the species originated in more than one geographical location.

Due to adaptions and evolution it may be difficult to tell which version came from the original and which are evolved, without knowing which is the original it can be hard to pin where its origin is. Another difficult thing can be that over time humans transported certain species and spread them which also makes it difficult to pin point their origin without knowing where they took them from.

If the species is found all around the world it might be hard to pinpoint exactly where it came from. Another factor that could make it harder to pinpoint the center of origin is if the animal is endangered and there aren't many specimens to research and look at.

After they start adapting to new environments they will stop showing traits that would've linked them to their area of origin.

The more species adaptations and the further they are from the equator the harder it will be to find the point of origin

Animals that dispersed and were able to move from one continent to another.

The very dispersion and diversity of a species may make it hard to trace an animal back with it's long genetic lineage and the dispersal of the species all over the world.

They show the path of evolution and how the dispersal of the species represent different adaptation.

If the animal evolved and changed, or if the location is now unable to access.

Different evolutionary paths look like a tree that shows the traits that have been passed down through generations. We can map them by looking at genetic traits that are shared between different species and their ancestors

If a predator of the species moves into the area, that species will be forced to move or face the threat of extinction.

animals evolve which often entails losing different body structures which could have helped find their center of origin. We can see this in the flightless birds that we've talked about throughout the year. They all flew to where they are, however they are incapable of flying now.

the animal could continue to evolve and adapt to the environment around it and move to accommodate food and space making it hard to fine the center of origin.

the range might be large and continents move and change over time.

The animal could have migrated and decided to stay. Another opposition could have been that the animal migrated and died because of lava eruption.

if the species adapts and then the original for of the species goes extinct

A species over time can move all over the world and adapt to fit that environment so it would be hard to discover where the species originated from

Threat of new predators, or an animal that has evolved over time.
