Many empirical studies have found evidence for the theory. Primates, including humans, are able to quickly detect snakes. [6] [7] Some studies have found that humans can detect snake images before subjective visual perception. [8] However, the pre-conscious detection of snake stimuli is still under debate by the scientific community. [9]
Results from this study suggest that current evidence for general intelligence is weak in non-human animals. [ 130 ] The general factor of intelligence, or g factor , is a psychometric construct that summarizes the correlations observed between an individual's scores on various measures of cognitive abilities .
The eponymous Silurians on Doctor Who are a race of reptilian humanoids from Earth's past, making their first appearance in the show in 1970. Frank and Schmidt cite Inherit the Stars, a 1977 novel by J. P. Hogan as containing a similar hypothesis, but also say they were surprised by how rarely the concept was explored in science fiction.

Early snakes had vestigial limbs, with the oldest-known fully limbless snake living around 85 million years ago, according to George Washington University evolutionary biologist and study co ...
Scientists hold the head of a northern green anaconda, a newly discovered snake species. This article originally appeared on USA TODAY: Photos: 'Magnificent' northern green anaconda, largest ever ...
But experts studying the creatures discovered that the newly identified northern green anaconda species diverged from the southern green anaconda almost 10 million years ago, and they differ ...
The human brain contains 86 billion neurons, with 16 billion neurons in the cerebral cortex. [ 2 ] [ 1 ] Neuron counts constitute an important source of insight on the topic of neuroscience and intelligence : the question of how the evolution of a set of components and parameters (~10 11 neurons, ~10 14 synapses) of a complex system leads to ...
Though these criteria are difficult to measure in nonhuman animals, cephalopods are the most intelligent invertebrates. The study of cephalopod intelligence also has an important comparative aspect in the broader understanding of animal cognition because it relies on a nervous system fundamentally different from that of vertebrates.
