Competition Breeds New Fish Species


Size differences among the Telmatochromis temporalis and competition for breeding space lead to the formation of new species, according to a new study.  This process is called Speciation.  Speciation occurs when genetic differences between groups of individuals accumulate over time.  In this case, the larger fish were posing a threat to the smaller fish.  The smaller fish then began moving their habitat from the rocky shores to the cluster of snail shells on the sand.  The smaller fish began living and breeding in the small snail shells.  This became he norm for the smaller fish, making this their niche.












Themes of Nature of Science:
Role of Credibility- This experiment and its contents were studied by biologists at the University of Bristol.
Role of Skepticism- Many people believe that this data is insufficient in supporting the idea of a "species separation."

  1. Another good Nature of Science theme would have been Science is Collaborative. Multiple biologists have experimented with this particular topic. Overall great points and a fascinating article!

  2. This is a very interesting article because when I did a lit more research I found that this happens everywhere. Animals are moved out from their normal habitats and moved into a new one because of apposing threats, such as a bigger animal. They will stay there and teach their offspring that where they are is safe and a good place to breed and live. It is very interesting to see so many similarities not only in the water but also on land.

  3. This is very interesting. I think its cool how the smaller fish just found another way to survive, and from Danny's comment, it sound like this happens a lot. It would be very cool to see more examples of this in real life.
