“INTERNAL SEXUAL REPRODUCTION is where the sperm fertilizes the egg within the female (mammals, birds, spiders, insects, reptiles). This is suited for terrestrial creatures whose sperm readily dries out and dies.” https://lnkd.in/e3_feD9 View in LinkedIn

“SEXUAL SELECTION among competing males for female impregnation may explain why males exist. It acts as a filter to weed out harmful genetic mutations allowing the survival of the population.” https://lnkd.in/e3_feD9 View in LinkedIn

THE RUB. “There has been controversy between more traditional views of increased biodiversity through a cone of diversity with the passing of time and the view that the basic pattern on Earth has been one of annihilation and diversification.” https://lnkd.in/efCSXC8 View in LinkedIn

POINTY END OF A CONE. “What we see today is the standing diversity—the net difference between cumulative speciation (births) and extinction (deaths)—which is a minute fraction of all the species that have ever lived.” https://lnkd.in/e5XfdvZ View in LinkedIn

WIPEOUT TRAIN. “More than 99 percent of all species, amounting to over five billion species, that ever lived on Earth are estimated to be extinct.” Would you voluntarily board this train with its reckless driver? https://lnkd.in/efCSXC8 View in LinkedIn

DEAD CLADE WALKING. “Clade survival is no guarantee that preextinction trends will persist or be reasserted in the postextinction setting. Each extinction has examples of clades that survived the extinction event only to fall into a marginal role or eventually disappear (dead clade walking).” http://www.pnas.org/content/98/10/5393.full/Donnie) View in LinkedIn

INEXORABLE MARCH. “The cumulative fossil record can give the impression that the diversity of life has increased inexorably through time, although punctuated with occasional mass extinction events.” (PS: See Figure 1). https://lnkd.in/e5XfdvZ View in LinkedIn

MINOR SETBACKS. “Other trends suffer setbacks—presumably owing to the contrast between mass extinction and “normal” selectivities—but then resume their long-term trajectories.” https://lnkd.in/epHhn4i) View in LinkedIn

FRAGMENT FROM NATURE grapples with two opposing viewpoints of evolution: that life is on a linear march towards increased diversity and complexity, versus the view of evolution as a highly destructive boom and bust pendulum. Explosive biodiversity has been the hallmark of the Cambrian period, while five mass extinctions have endangered the very crucible of life on planet earth. View in LinkedIn
