“NO NEW PHYLA have evolved since the Cambrian.” Meditate on this one. https://lnkd.in/ex6BW5w View in LinkedIn

NEGATIVE CORRELATION. "In semelparous plants, a trade-off between survival and reproduction is supported by both experimental and comparative evidence. Various methods of preventing reproduction can extend life span, and reproductive effort is negatively correlated with life span across species." https://lnkd.in/ecP3KMX View in LinkedIn

SINGLE CAMBRIAN ORIGIN. “Evidence of metazoan activity in both trace and body fossils then increased during the 13 million years leading to the explosion. All living phyla may have originated by the end of the explosion.” http://dev.biologists.org/content/develop/126/5/851.full.pdf View in LinkedIn

GENETICS-FIRST CAMP "find implausible the idea that molecular networks without genetic control could have undergone Darwinian evolution." https://lnkd.in/euzMX5X View in LinkedIn

METABOLISM-FIRST CAMP. "There are two camps in the origin of life. The metabolism-first camp advocates consider improbable that RNA-like self-replicating polymers appeared before natural selection had operated on chemical networks." https://lnkd.in/euzMX5X View in LinkedIn

DEATH OR REPLICATION. "Natural selection is a mechanism by which populations adapt and evolve. In its essence, it is a simple statement about rates of reproduction and mortality: Those individual organisms who happen to be best suited to an environment survive and reproduce most successfully, producing many similarly well-adapted descendants." Impressive. https://lnkd.in/eaizZgz View in LinkedIn

SELECTIVE PROCESS. "Natural selection is the gradual, non-random process by which genetically inherited traits (alleles) become either more or less common in a population due to non-random differences in the effective reproductive rate of bearers of these genetic traits." https://lnkd.in/eS_4y_J View in LinkedIn

PREFERENTIAL SURVIVAL. "Natural selection is the differential reproduction of genotypes. ‘Natural selection […] is the differential and non-random reproduction of different alternative alleles in a population’...population genetics and modern evolutionary theory equate natural selection with differential reproduction of alternative forms of genes, genotypes, or other reproducible units’." Lovely definition. https://lnkd.in/eS_4y_J View in LinkedIn

"WHY A HIGHER MUTATION RATE occurs in the mitochondria in contrast to the nucleus appears related to the generation of genetic diversity useful in exploiting new ecological niches. In particular, the enzymes involved in energy generation by the mitochondrion. The mitochondrion is the powerhouse of the cell." https://lnkd.in/e533NK2 View in LinkedIn
