"With the possible exception of Asa Gray, no American read the Origin of Species with as much care and insight as Henry David Thoreau.... That the struggle among species was an engine of creation struck him with particular force. It undermined transcendentalist assumptions about the essential goodness of nature, but it also corroborated many […]
(McMaster University) New biological information gleaned from the red vizcacha rat, a native species of Argentina, demonstrates how genomes can rapidly change in size.Researchers from McMaster University set out to study this particular species because its genome, or its complete set of DNA, is the largest of all mammals, and appears to have increased in size very rapidly.
New biological information gleaned from the red vizcacha rat, a native species of Argentina, demonstrates how genomes can rapidly change in size.
(University of Turku) Throughout the history of life, new groups of species have flourished at the expense of earlier ones and global biodiversity has varied dramatically over geologic time. A new study led by the University of Turku, Finland, shows that completely different factors regulate the rise and fall of species.
(University of California - Berkeley) Based on earlier studies, biologists believed that the vast majority of today's frogs originated in a blossoming of new species 100 million years ago. New and more complete genetic data pinpoints...Show More Summary
This article was originally published on The Conversation. Read the original article. Of all the species that have ever lived, more than 99 percent are now extinct. Most of them quietly disappeared during periods of “background extinction,” whereby a handful of species become extinct every 100,000...

Since its first incarnation, Star Trek has been about multiculturalism, with characters of different species living and working together on the Starship Enterprise. The original series featured a diverse cast and even included the first interracial kiss ever shown on TV. Show More Summary
The News & Views article 'Palaeoanthropology: On the origin of our species' by Chris Stringer and Julia Galway-Witham (Nature546, 212–214; 2017) stated that at least five individuals were identified from human fossils uncovered in excavations reported by Hublin
(Louisiana State University) Biologists have always been fascinated by the diversity and changeability of life on Earth and have attempted to answer a fundamental question: How do new species originate?A new study provides the first large-scale test of the link between population differentiation rates and speciation rates.

The findings may push back the origin of our species by more than 100,000 years and challenge leading ideas about where and how our lineage evolved. Continue reading ? The post Ancient fossils from Morocco mess up modern human origins appeared first on PBS NewsHour.
New finds of fossils and stone tools from the archaeological site of Jebel Irhoud, Morocco, push back the origins of our species by one hundred thousand years and show that by about 300 thousand years ago important changes in our biology and behaviour had taken place across most of Africa.
This post originally appeared on The Conversation. Cuba is the ecological crown jewel of the Caribbean. It harbors thousands of the region’s endemic species and about half of its coastal ecosystems. It is rare to find comparable ecosystems...Show More Summary
I had previously called Irhoud 1 "The Father of Mankind" and proposed a "two deserts" theory of human evolution whereby our species originated in North Africa, and was pumped out of it to both the Middle East (and especially Arabia, the 2nd desert) and Sub-Saharan Africa during periods of Saharan aridity.

The oldest known bones of our species, dating back around 300,000 years, have been discovered in a cave in Morocco.
New fossil finds from the Jebel Irhoud archaeological site in Morocco do more than push back the origins of our species by 100,000 years.
The remains of five early Homo sapiens have been unearthed at a site in northwest Africa. At around 300,000 years old, the fossils are a whopping 100,000 years older than the previous record, pushing back the origin of our species by a significant margin. Show More Summary
Fossils discovered in Morocco are the oldest known remains of Homo sapiens, scientists reported on Wednesday, a finding that rewrites the story of mankind’s origins and suggests that our species evolved in multiple locations across the African continent.
Fossilized remains found in Morocco might belong to our 300,000-year-old ancestors. The skulls and bones could represent the earliest known fossils of Homo sapiens, the human species to which we all belong, scientists said in two new studies published Wednesday. Show More Summary
The understanding of human origins was turned on its head on Wednesday with the announcement of the discovery of fossils unearthed on a Moroccan hillside that are about 100,000 years older than any other known remains of our species, Homo sapiens. Scientists determined that skulls, limb bones and...
