EVODEVO PERSPECTIVE. "As gene regulatory networks and their interactions provide evolvability to the process of organismal development, understanding how networked genes and/or their interactions are selected upon to yield novel outputs is the future for evodevo, especially for researchers interested in understanding how particular adaptive traits might have evolved." https://lnkd.in/dD4GcAS View in LinkedIn

SO ENDS this peek into floral fusions and where they came from. Evolution is not something that ends, and the process continues. Where are flowers headed next in this continuum of change and adaptation? View in LinkedIn

RARE MUTATION ACCUMULATION. "Of the thousands of random changes created every day in the DNA of a human cell by heat, metabolic accidents, radiation of various sorts, and exposure to substances in the environment, only a few accumulate as mutations in the DNA sequence." https://lnkd.in/dHtn_RS View in LinkedIn

DNA REPAIR. "We now know that fewer than one in 1000 accidental base changes in DNA results in a permanent mutation; the rest are eliminated with remarkable efficiency by DNA repair." https://lnkd.in/dHtn_RS View in LinkedIn

NUMEROUS SAFEGUARDS. “There are multiple pathways for DNA repair, using different enzymes that act upon different kinds of lesions." https://lnkd.in/dHtn_RS View in LinkedIn

COMPLEXITY BEGETS DEATH. "Death is not only for humans. All 'complicated enough' organisms die (with a notable exception of Hydra, tough you may argue when it comes to the complexity)." https://lnkd.in/di9iHQe View in LinkedIn

REPAIR IS HARD. "It is is easier to create a new organism from scratch than to repair both internal factors (free radicals, metabolic by-products, ...) and external (physical damage, exposure to toxins, ...)." http://biology.stackexchange.com/questions/1495/what-evolutionary-explanations-are-there-for-death View in LinkedIn

THE EVOLUTION OF DEATH in the natural world will give insights to the biological function of death in living things. To the extent that this is even feasible will be examined herein. View in LinkedIn

SINGLE CELL BEASTS MAY NOT NEED DEATH. "It has been argued that for unicellular organisms, there would a priori appear to be no need for such a program, as cell death basically translates into organismal death and therefore would confer no evolutionary advantage (dead organisms do not procreate)." https://lnkd.in/dVeZ2yE View in LinkedIn

DEATH CAN GENERATE NOVELTY. "On the evolutionary scale, selective use of programmed cell death can also lead to the creation of novel structures. For example, the gonadal lineages in C. elegans hermaphrodites and Panagrellus redivivus females are very similar, even though the gonads of these animals are quite different." https://lnkd.in/dVeZ2yE View in LinkedIn
