Sentence examples for molecular clock dates from inspiring English sources

From these studies, it is clear that many of the core clock genes are conserved in these two disparate animal groups [10], suggesting that this molecular clock dates back to at least the ancestor of deuterostomes and protostomes.

Molecular clock dates are key to being able to discriminate between vicariance and dispersal hypotheses [e.g., [ 16]].

The molecular clock dates suggest that early animals fossilized poorly, possibly because they were small and soft-bodied.

Minimum ages for blocks found in different species were estimated by reference to molecular clock dates for relevant taxon divergences (Table 2).

Currently a debate exists as to whether divergences among animals are best represented by molecular clock dates or the fossil record [ 33- 37].

Relaxed molecular clock dates provide age estimates for the LT flock at ~7-8 Myr, indicating intralacustrine diversification, with further speciation events coinciding with periods of lower lake level.

Molecular clock dating indicates it reached Haiti roughly in 1966.

Molecular clock dating shows that M reached humans somewhere near 1921.

The oldest fossil "proto-frog" appeared in the early Triassic of Madagascar, but molecular clock dating suggests their origins may extend further back to the Permian, 265 million years ago.

For molecular phylogenetics and molecular clock dating, total DNA was extracted from wild-caught and lab-reared Deltophora adults and larvae using standard methods.

DNA sequences placed the moths and plants phylogenetically and confirmed that larvae were those of the pollinating moths; molecular clock dating suggests that the moth clade is younger than the plant clade.
