The segments of vertebrates and cephalochordates are so similar that they were almost certainly present in the common ancestor of the two groups.
I know from my conversations with American and Ukrainian scientists that minute traces of radioactive cesium and strontium are almost certainly present in some, if not all, of the food grown in this region.
Nonetheless, the effect is almost certainly present.
The study concluded that it was impossible to determine whether prosauropods had a bird-like flow-through lung, but that the air sacs were almost certainly present.
Repetitive sequences in tandem are problematic for de novo assembly algorithms and these tRNAs are almost certainly present in our eight strains, despite the fact that they are not present in contigs.
Disorder of the magnitude represented in our simulations is almost certainly present in actual basilar papillae, in which the number and arrangement of hair cells varies from row to row [19], [20].
Vertically migrating small fish prey are almost certainly present in the Gulf Stream as well, with myctophids in the central equatorial Atlantic all vertically migrating to depths of up to 1250 m during the day, with central daytime distributions centred at 400 700 m [50].
By default, therefore, this gene is almost certainly present in the nuclear genome.
Some degree of unobserved confounding is almost certainly present in most observational studies.
