Which of the following group is most closely related to mammals quizlet
(The phylogenetic trees branching pattern clearly shows that mammals are most closely related to reptiles.)
Do all mammals give birth
2. Reptiles – Most lay eggs, but there are many snakes and lizards that give birth to live young. 3. Mammals – Almost every mammal gives live birth (with the exception of the platypus and the echidna).
Which subgroup of mammals do humans belong to

Why are mammals teeth unique quizlet
You just learned five terms: how many different species of mammals exist, why are mammal teeth special, and what do different teeth in mammals do?
Are mammals Ectotherms
The only true warm-blooded animals left today are mammals and birds, which are classified as endotherms because they generate their own internal body heat as opposed to ectotherms, which derive their heat from sources like the sun.
Do all mammals have mammary glands
(Although not all mammals have breasts, all mammals have mammary glands, and some mammals dont even have nipples.
Which animal group is characterized by the absence of tails
Because of their long hind limbs and lack of a tail, frogs and toads (order Anura) are easily distinguished from other animals.
What are some features that are unique to primates quizlet
- larger frame.
- diminutive ears
- sophisticated social behavior
- Stereographic perception
- entire orbit.
- a bigger brain
- more parental attention.
Which of the following lifeforms ruled the Earth for the longest time than any other life
Even though these living things have been around for a while, cyanobacteria, a tiny organism that you would probably need a microscope to see, is one that has largely outlasted the others.
Which features are shared by both a sea star and a human but not a jellyfish
Both are bilaterally symmetrical, but neither a jellyfish nor a sea star has this characteristic.
Which statement accurately describes human evolution
Which of the following best describes how humans evolved? A. Human evolution came to an end 200,000 years ago when Homo sapiens separated from other species.
What makes a mammal a mammal quizlet
The class of endothermic vertebrates known as mammals includes creatures like bats, whales, mice, and humans. Mammals also have four limbs and lay amniotic eggs.
What do all mammals have in common quizlet
Warmblooded, hair, mammary glands, lungs, and a four-chambered heart are three additional traits that most mammals share.
What are the two characteristics of all mammals quizlet
List the five characteristics that all mammals possess.
- heart with four chambers.
- Hair.
- Breast glands.
- Internal framework.
- being able to internally regulate their body temperature (warm-blooded)
What are the two distinguishing characteristics of mammals
Female mammals have mammary glands, which produce milk after the birth of offspring. These glands are two characteristics that are used to define the mammal class.
What characteristics do birds and mammals share
Existing birds and mammals have a number of traits in common, such as improved hearing, vocal communication, endothermy, insulation, shivering, respiratory turbinates, high basal metabolism, sustained activity, four chambered heart, high blood pressure, and intensive feeding.
