The new species evolved when the orchid moved farther away from it's original pollinators. The cricket depends on the orchid for nectar as food, as the cricket can find no other source. The orchid needs the cricket to help pollinate (or spread the plant seeds) because the plant cannot pollinate itself, nor is it in an area where it's original pollinators, such as birds and bees, are living. These two species are in a state of co-evolution, wherein both have evolved so as to mutually benefit the other species.
ReplyDeleteThe new species evolved because the flower moved away. the species depends on th flower for food. Its needs the criket to be polinated. they have both evolved to benefit from others and its self to better adapt to its environment.
ReplyDeleteThats really interesting how crickets have evolve and change over time. Well i remmember whem mom use to listen with me how the crikets sing and I asked mom what they ate and she siad they ate plants and gras. Now that am older i can be able to tellmy children that there is a new specie of crikets. That is really interesting how species can change over time. I wonder if humans would ever change over time.
ReplyDeleteThe new species envolved because crickets depends on the orchid . Glomeremus crickets belongs to family with relatives that goes back to a nest each night .
ReplyDeleteIt seems like many animals would pollinate, because almost every insect eats vegetation. I found it very interesting how the cricket puts its entire head into the pollen. It is also fascinating how the cricket could use the pollen scent to make a trail from each area it’s been to and being able to track where it’s been. I bet there is more than just one species of crickets that pollinate, and I think there are more discoveries to be found.
ReplyDeleteThis is an example of mutualism. The orchid gets its pollen spread while the cricket gets nectar from the orchid. They became so dependent on each others survival that they evolved together. As a result of this evolution, this cricket became a new species that pollinates flowers.
ReplyDeleteI assume the new species evolved through the orchids seeds spreading and as a result a different breed of crickets formed through survival of the fittest. The orchid depends on the cricket to spread its pollen so it's kind will continue. I think because these two species have become so dependent on each other they will continue to progress together.
