UPPER LIMIT OF HUMAN LONGEVITY is estimated at 80-120 years, but more likely 85 years due to the disease burden. https://lnkd.in/dkbhh-F View in LinkedIn

REMARKABLE FACT. "We can illustrate the conserved features of sexual reproduction by comparing the sexual cycles for two of our favorite systems: ourselves (Homo sapiens) and the model yeast Saccharomyces cerevisiae. Despite having diverged ~ one billion years ago, the core features of sexual reproduction are conserved." http://www.mycologia.org/content/105/1/1.full View in LinkedIn

CONSERVED YET PLASTIC. "Given the ubiquity of sex, it is remarkable both how conserved the core features are and yet how plastic other aspects appear to be, including how sex is determined and how sexual reproduction is accomplished." http://www.mycologia.org/content/105/1/1.full View in LinkedIn

REVEALING HIDDEN GENETIC VARIATION. "Sex—the mixing of genomes via meiosis and fusion of gametes—is nearly universal to eukaryotic life and encompasses a diverse array of systems and mechanisms. One major role of sex is to bring together alleles carried by different individuals, revealing beneficial genetic variance that is otherwise hidden." https://lnkd.in/eK75j6J View in LinkedIn

EUK LIFE CYCLE #3. "Observed in all plants and some algae, species with alternation of generations have both haploid and diploid multicellular organisms as part of their life cycle.” https://lnkd.in/dvZ2tF3 View in LinkedIn

EUK LIFE CYCLE #2. "Most fungi and algae employ a haploid-dominant life cycle type in which the "body" of the organism is haploid; specialized haploid cells from two individuals join to form a diploid zygote. https://lnkd.in/dvZ2tF3 View in LinkedIn

EUK LIFE CYCLE #1. "In the diploid-dominant cycle, the multicellular diploid stage is the most obvious life stage; the only haploid cells produced by the organism are the gametes." https://lnkd.in/dvZ2tF3 View in LinkedIn

3 TYPES OF LIFE CYCLES IN EUKS. "The main categories of sexual life cycles in eukaryotic organisms are: diploid-dominant, haploid-dominant, and alternation of generations." https://lnkd.in/dvZ2tF3 View in LinkedIn

SEX AND EUKS. "Given that sexual reproduction is pervasive and extant in all of the major super groups of the eukaryotic tree of life, it is hypothesized the sex emerged once in an ancestral eukaryote and has been preserved and conserved throughout the eukaryotic tree of life. Thus, one can think of the ability to undergo sexual reproduction as a synapomorphy for the eukaryotes." http://www.mycologia.org/content/105/1/1.full View in LinkedIn

PROK VS EUK. "Key features that distinguish eukaryotic from prokaryotic organisms are the presence of the nucleus and other intracellular organelles (mitochondria, chloroplasts, Golgi, endoplasmic reticulum), the emergence of multicellularity and the ability to undergo true sexual reproduction." http://www.mycologia.org/content/105/1/1.full View in LinkedIn
