 | 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. |

If they traveled and died somewhere further from their habitat.

It can be difficult to tell where an animal originated because there could be a lack of fossils that date back far enough.

When a species shows up in an area that there are no other species like it for it to adapt from or if there are no other species except for the one individual

one factor that could complicate determining the center of origin of a species would be different forms of vicariance. with animals being all over the world and adapting to wildly different environments it can be hard to trace.

If they have traveled far away, it can cause trouble in identifying where the animal originated from

The animals could be migratory and spread out or there could be little fossil evidence to support the center of origin.

It will turn complicated if the species moves away or dies.

One thing that could complicate finding the Center of Origin could be the change of land over time. Ex. Certain land bridges an animal may have traveled on might not be there anymore.

Animals could’ve spread out across the whole globe and fossils don’t go back far enough so it’s hard to tell where they originated.

One thing that would complicate the center of origin is if the center of origin is no longer accessible (underwater, eroded,...)

the land the species is from could have been not good for preserving fossils, making evidence hard to find

It might be difficult to find a specie's center origin because the resource that they might have used might have changed so they would have to adapt and move away from the center.

The area that the animals are native to could have changed so much. That we could not find the fossils. (Like underwater)

It can be more difficult if there is little to no fossil evidence Leave a Reply. |
