The Evolution of Air Breathing in Vertebrates

First released in 1981, this booklet offers an unique method of a space of serious significance in comparative zoology and body structure and evolutionary biology: the evolution of air inhaling vertebrates from aquatic ancestors. the topic is approached from a sensible in addition to an anatomical standpoint, using wisdom of the body structure of extant animals to track possible evolutionary steps.

Last's Anatomy: Regional and Applied, 12e

This nearby textbook of anatomy is aimed toward trainee surgeons and clinical scholars. all through it really is wealthy in utilized scientific content material, wisdom of that is crucial for either scientific exam and surgeries. even supposing local in process every one bankruptcy is based to obviously clarify the constitution and serve as of the part platforms.

Biomarkers in Neoplastic Neuropathology

This e-book is a wealthy resource of data on biomarkers appropriate to the pathology of neoplastic problems of the mind. Thorough descriptions are supplied of the concepts at the moment on hand for medical and experimental review of biomarkers in mind neoplasms, together with in situ hybridization, array-based tools, methylation profiling, next-generation sequencing, and functional gene panels.

Example text

They have strong limbs and are fast runners. They also have scaly eyelids, conspicuous ear openings, pointed heads, elongate bodies and tails, and bodies usually patterned by stripes, checks, crossbars, or spots. Most species are bisexual, but about 15 unisexual biotypes—some diploid and some triploid—are known within the family. , 2002). The genus Aspidoscelis (formerly Cnemidophorus, in part) includes about ten recognized taxa that are either parthenogenetic or include parthenogenetic lineages (Wright and Vitt, 1993), an example of which is detailed below.

Sporadic Natural Parthenogens All of the unisexual biotypes described above perpetuate clonal lineages by obligatory or constitutive parthenogenesis. , 2003) occurs sporadically in a few sexual vertebrates. Zookeepers have long suspected that some bisexual species are capable of tychoparthenogenesis, based on an observation that females maintained in long-term isolation occasionally produce viable offspring. Molecular genetic assays have confirmed that some such progeny do carry their mother’s DNA only, and thus indeed had a single parent.

All forms of clonal reproduction begin with the faithful replication of genetic material. 3. The clonal propagation of genetic material (nucleic acids) normally relies on the informational redundancy inherent in the double-stranded structure of duplex DNA. During mitosis, nuclear genomes are clonally copied during the proliferation of an individual’s somatic cells, all of which trace back to a single cell (a fertilized egg or zygote in sexual species). A multicellular individual can hence be viewed as a tight-knit colony of clonemate cells.
