The level of support for evolution among scientists, the public, and other groups is a topic that frequently arises in the creation–evolution controversy, and touches on educational, religious, philosophical, scientific, and political issues.
Evolutionary theory predicted that since amphibians evolved from fish, an intermediate form should be found in rock dated between 365 and 385 million years ago. Such an intermediate form should have many fish-like characteristics, conserved from 385 million years ago or more, but also have many amphibian characteristics as well.
There is considerable support for faster rates of genetic evolution in warmer environments, [26] some support for a slower rate among plant species where water availability is limited [31] and for a slower rate among bird species with small population sizes. [32] Many aspects of the hypothesis, however, remain untested.
Milford Howell Wolpoff is a paleoanthropologist and professor of anthropology at the University of Michigan and its museum of Anthropology. He is the leading proponent of the multiregional evolution hypothesis that explains the evolution of Homo sapiens as a consequence of evolutionary processes and gene flow across continents within a single species.
Professor of biology Jerry Coyne sums up biological evolution succinctly: [3]. Life on Earth evolved gradually beginning with one primitive species – perhaps a self-replicating molecule – that lived more than 3.5 billion years ago; it then branched out over time, throwing off many new and diverse species; and the mechanism for most (but not all) of evolutionary change is natural selection.
Soil studied by India’s Chandrayaan-3 mission near the lunar south pole adds support to the theory that the moon once had a magma ocean billions of years ago.
The mediaeval great chain of being as a staircase, implying the possibility of progress: [1] Ramon Lull's Ladder of Ascent and Descent of the Mind, 1305. Alternatives to Darwinian evolution have been proposed by scholars investigating biology to explain signs of evolution and the relatedness of different groups of living things.
