Define Comparative Anatomy
Is the study of similarities and differences among structures of living species
Give a example of Homologous Structure
(humans,Cats,frogs,and birds use their different things the forelimb bones exhibit similar patterns)
What a pharyngeal pouches
at one stages which develops into different parts in each vertebrate (face,neck,hands,arms)
Comparative Anatomy is the study of similarities and differences among structures of living species
True
Homologous Structure
Give a example of Analogous structures
( bird wings are covered in feathers and flies are covered in hair)
often resemble each other at different stages of their development
Embryos
Analogous are body parts that have lost their original function through evolution
False
Define Embryology
Is the science of the development of embryos from fertilization to birth
-------such as forelimbs suggest species are distantly related
Homologous Structures
What is the science of the development of embryos from formalization to birth
Embryology
Scientists use this molecular clock to estimate at what time in the past living species diverged from common ancestors
True
Are body parts that perform a similar function but differ in structure
Analogous Structure
Species with a ------ that is related to an ancestral species that used the structure for a specific purpose but now don't
Vestigial Structures
What is Molecular biology
Is the study of genes structure and functions
Molecular is the science of the development of embryo from fertilization to birth
False
Define Vestigial Structures and give example
Are body parts that have lost their original function through evolution( humans have wisdom teeth and are now removed)
Name and define all Structure
Analogous- similar function but differ in structure
Vestigial Structure- lost their original function
Homologous-Similar structure but different Function
Is the study of similarities and differences among structures of living species
Comparative Anatomy
Double BONUS: WHAT IS A molecular clock
to estimate at what time in the paste living
