Adaptation and adaptive radiation

Geoffrey E. Hill.

in Mitonuclear Ecology

April 2019; p ublished online June 2019 .

Chapter. Subjects: Animal Pathology and Diseases; Evolutionary Biology; Genetics and Genomics. 19444 words.

A key outcome of evolution by natural selection is adaptation. Since the beginning of the age of genetics, evolutionary biologists have focused on the evolution of nuclear genes as the...

Coevolution, co-transmission, and conflict

Geoffrey E. Hill.

in Mitonuclear Ecology

April 2019; p ublished online June 2019 .

Chapter. Subjects: Animal Pathology and Diseases; Evolutionary Biology; Genetics and Genomics. 8263 words.

Mitochondrial genes and nuclear genes are replicated and transmitted across generations as physically separated units. The extent to which these autonomous genomes are co-transmitted...

Compensatory coevolution

Geoffrey E. Hill.

in Mitonuclear Ecology

April 2019; p ublished online June 2019 .

Chapter. Subjects: Animal Pathology and Diseases; Evolutionary Biology; Genetics and Genomics. 11876 words.

In most eukaryotes, mitochondrial genes mutate at a higher rate than nuclear genes. In addition, mitochondrial genes are transmitted without recombination, so slightly deleterious mutations...

Epilogue

Geoffrey E. Hill.

in Mitonuclear Ecology

April 2019; p ublished online June 2019 .

Chapter. Subjects: Animal Pathology and Diseases; Evolutionary Biology; Genetics and Genomics. 2025 words.

Evolutionary ecology is at the precipice of a paradigm shift. For many years and through the early years of the 21st century, mitochondrial genomes were dismissed as unimportant to the...

The evolution of sex and two sexes

Geoffrey E. Hill.

in Mitonuclear Ecology

April 2019; p ublished online June 2019 .

Chapter. Subjects: Animal Pathology and Diseases; Evolutionary Biology; Genetics and Genomics. 9433 words.

Sexual reproduction has proven so formidable a challenge for evolutionary biologists that it is commonly spoken of as “the paradox of sex.” Stated simply, individuals forsake one-half of...

Forms and consequences of incompatibility

Geoffrey E. Hill.

in Mitonuclear Ecology

April 2019; p ublished online June 2019 .

Chapter. Subjects: Animal Pathology and Diseases; Evolutionary Biology; Genetics and Genomics. 12655 words.

To understand the evolutionary consequences of poor coadaptation of mitochondrial and nuclear genes, it is necessary to consider in molecular detail the manifestations of mitochondrial...

The genomic architecture of eukaryotes

Geoffrey E. Hill.

in Mitonuclear Ecology

April 2019; p ublished online June 2019 .

Chapter. Subjects: Animal Pathology and Diseases; Evolutionary Biology; Genetics and Genomics. 7819 words.

Eukaryotes are chimeras—the product of an ancient fusion of a bacterium and an archaeon. Mitochondrial genomes only code for a few dozen products, so more than 1000 nuclear genes create...

Life eternal in the face of senescence

Geoffrey E. Hill.

in Mitonuclear Ecology

April 2019; p ublished online June 2019 .

Chapter. Subjects: Animal Pathology and Diseases; Evolutionary Biology; Genetics and Genomics. 11480 words.

Unlike prokaryotes, eukaryotes are born, mature, grow old, and die. Why death is inevitable for all complex life is among the most important questions in evolutionary biology. The...

Mitonuclear Ecology

Geoffrey E. Hill.

April 2019; p ublished online June 2019 .

Book. Subjects: Animal Pathology and Diseases; Evolutionary Biology; Genetics and Genomics. 320 pages.

Eukaryotes were born of a chimeric union of two prokaryotes. The legacy of this fusion is organisms with both a nuclear and mitochondrial genome that must work in a coordinated fashion to...

Mitonuclear mate choice

Geoffrey E. Hill.

in Mitonuclear Ecology

April 2019; p ublished online June 2019 .

Chapter. Subjects: Animal Pathology and Diseases; Evolutionary Biology; Genetics and Genomics. 8572 words.

At each new generation, sexual reproduction creates new combinations of nuclear and mitochondrial genes, and the potential arises for mitonuclear incompatibilities and reduced fitness....

Mitonuclear speciation

Geoffrey E. Hill.

in Mitonuclear Ecology

April 2019; p ublished online June 2019 .

Chapter. Subjects: Animal Pathology and Diseases; Evolutionary Biology; Genetics and Genomics. 15310 words.

Current models of speciation assume that species arise when nuclear genotypes diverge following the disruption of gene flow between populations. This chapter explores the idea that...
