Question

In this case, we have a large population of lizards that live on an island. These particular lizards can either have an all-green tail or a tail with a black tip. In the large population there are many of each type, but one day, two green-tailed lizards and three lizards with black-tipped tails were picked up by a sailor and dropped off on an island that had no lizards of this kind. It was noted that the black-tipped lizards could use the black tip of their tail to distract predators while they made a quick escape and this particular island had many predators. The lizards began to breed and eventually produced their own large population after a few years. Make a prediction about what you might find if you visited this island after several years based on what you have learned.
PLEASE HELP!!!

Answer 1

This is a complicated question that's a little easier if you break it down!

Island One:

- Lizard tails are all green or black tipped.

- This island has many of each type.

Sailors Moved:

- two green-tailed lizards

- three black-tipped lizards

On Island Two, we know that the black-tipped lizards are more likely to survive since the question tells us that "the black-tipped lizards could use the black tip of their tail to distract predators while they made a quick escape and this particular island had many predators".

The green tailed lizards do not have this advantage, and the predators are eating more of them because of this (especially if there are a lot of predators!).

We also know that the lizards on the island were able to reproduce and form a large popuation- not all of them were eaten by predators.

Based on this information we can predict:

There are going to be a lot more black tipped lizards (or they may all be black tipped lizards) because they have an advantage in surviving longer.
