Speciation and Evolution: Analysis of Lizard Species and Environments

This report examines the process of speciation and its impact on species, using lizards as a case study. It discusses the definition of speciation and the factors that drive it, such as environmental changes like hurricanes, and the subsequent adaptation of species to new habitats. The report explores the hypothesis that lizards separated by natural events would develop distinct characteristics, and it outlines the methods used to study this, including the study of mouse and its interbreeding challenges. It highlights how factors like habitat, food availability, and climate influence species differentiation, leading to the emergence of new species over time. The report includes references to relevant research on evolution and species adaptation, providing a comprehensive overview of the topic.

Abstract
The present paper deals with the discussions about species and events after their separated.
This article deals with the definition of speciation and what are its effect on species. Are there
any physiological changes after the separation of species?
Purpose
The aim of this article is to provide the information about speciation and responses of
speciation. The explanation is depicted by an example of lizard species and what happen if it
is segregated into two groups due to the hurricane.
Introduction
Species is a cluster of living organisms which can be either animal or plant or small bacteria
which have close similarity with one another, and they can breed for producing offspring.
Speciation is defined as the event of evolution forming a novel and diverse species.
Hypothesis/Predicted Outcome
The lizards could develop different habits and characteristics which would be entirely distinct
from each other due to a different habitat.
Methods
The present study would study about lizards and their offspring by studying the mouse. As
per the species restriction, bear and mouse can’t interbreed. The study shows how the mouse
escapes o different island and creates a different species. Speciation could occur due to any
of the natural causes like hurricane, earthquake, and mountain sliding or water currents. The
difference in lifestyle and adaptation of region specific habitat develop a new species (Peichl,
2005).

Results/Outcome
Lizards’ species separated due to the natural action like a hurricane would cause these species
to differentiate and develop into two distinct species. This speciation is due to the change in
habitat, environment, food availability and climatic region growing characteristics changes in
appearance (Levins, 1968).
Discussion/Analysis
The laboratory analysis shows that new species would be created, but it requires time.
Speciation has resulted in several species generation, and therefore there can be different
species in the mainland.
