Comparing Birds and Mammals with Reptiles (Non - Avian), INTRODUCTION,…

INTRODUCTION
Unknown/Known Question
Mammals and birds are similar in that they are both endothermic species, and they have similar correlations with BMR to mass comparisons as well as body mass to mass-specific BMR comparisons. Does this mean that there will be the same correlations shown with non-avian reptiles and birds?
Will the non-avian reptiles be different from the birds because of them being exothermic and not endothermic?
Question and Hypothesis
How similar are the correlations of BMR and mass-specific BMR to the body mass of the reptile (non-avian) and birds (Aves)?
It is hypothesized that there will be a positive correlation between the same with both the reptiles (non-avian) and the birds regaurdless of them differing by blood being endothermic and exothermic
Background
Birds and reptiles came from the same ancestors. Despite the external features looking different to the human eye, birds and reptiles have several traits to show the connection to their prehistoric ancestors. Both types of creatures are branches under the class Reptilia. Like reptiles, birds lay eggs and have scales on their feet. There is one major difference that separates birds from reptiles, being that birds are endothermic species that have warm blood and reptiles (non-avian) are exothermic creatures that have cold blood.
Approach
Observation and analyzing the data extracted from the Quaardvark database and further online research will help to clarify the level of similarities and differences between the two species.
METHODS
Design
Various tests will be conducted via excel to compare the BMR to body mass and the mass - specific BMR to body mass in both non-avian reptiles and birds to give statistics needed for data.
Subjects
Birds (Aves) , Reptiles (non-avian), and mammals.
Materials
The Quaardvark database and excel will be used to collect information needed to form a conclusion as well as online primary sources.
Procedures
Using excel, t-tests assuming unequal variances, bar graphs, and scatter plots will be used in addition to online research after using the Quaardvark database.
ABSTRACT
Background
There was a similar correlation between the BMR and mass of birds and mammals in addition to there being a similar correlation between the mass-specific BMR and mass between birds and mammals. Since birds are the descendants of reptiles, it gives the assumption that there will be an almost identical correlation between the birds and (non-avian) reptiles.
Methods
Data was extracted from the Quaardvark database on the reptiles (non-avian) and the birds of their BMR, mass-specific BMR, and their body masses.
Results
The results of the correlation between birds and non-avian reptiles were shown base on the provided charted information.
